VScode SSH extension stuck on the installation step - visual-studio-code

For the past few months, I've used this VSCode Extension to work remotely on a linux server via SSH. I'll occasionally have a connection problem, but sshing from a terminal and deleting ~/.vscode-server/ has always fixed it. This time, though, that didn't fix it. I've tried deleting the folder multiple times, I've removed and reinstalled the VSCode extension, restarting my computer, everything I could think of. But each time, it gets stuck at downloading with wget, even if I leave it going for hours. I can connect to the server by sshing directly just fine, and other people I know can connect to the server through the extension as well. Is there anything else I can try to get this working?
Here's the full installation log (with the host name censored):

I ended up getting it working. I was connecting to a Centos7 server, what worked for me was deleting ~/.wget-hsts. After that, it reinstalled the server and connected fine.

There are a few reports of a similar issue in the microsoft/vscode-remote-release project which implements for VSCode this feature.
For instance, issue 4008
The remote OS I am connecting to is a RHEL 7 Linux machine.
I tried fiddling with iptables and ports for the wget request to no avail.
It hangs for a little while at the wget step, and ultimately fails to connect. I tried tweaking just about every SSH setting in the remote.
The only other thing I noticed that might be related was with the Ports Available text at the bottom of the screen. It never reads anything other than 0 during the connection process. When I'm properly connected, it says 1 Port Available.
However, I did find a successful workaround: I rolled back the Remote SSH extension to 0.55.0 and it worked like a charm again.
So try and downgrade the Remote SSH extension, to see if it works.

I tried waiting for around 10 minutes and it downloaded. Don't know why although ✨

VS Code Remote-SSH won't reconnect to one specific working directory on remote Ubuntu host

I'm using VSCode 1.72.2 with Remote-SSH v0.90.1 on Windows to develop against an AWS EC2 VM running Ubuntu 22.04 LTS. A couple days ago, I was working in my project source folder in /opt/t4/ on the target host. When I was finished, I stopped the VM from the AWS console, forgetting that VS Code was still SSHed in.
When I brought the VM back up, I can reconnect VS Code/Remote-SSH to the host as before, except that I can no longer connect using /opt/t4/ as my working directory. I can use any directory except the one I was using when I disconnected.
I can navigate down to it and work in it if I use /opt/ as my working directory. I can navigate to it by manually SSHing to the remote host. I can create a subfolder in a remote shell at /opt/t4/test/, and then connect VS Code using that subfolder as my working directory. I can see and select /opt/t4/ in the Open Folder dialog in VS Code. But when I try to connect using that working directory, the connection times out with a not-particularly-useful error message:

I tried Remote-SSH: Uninstall VS Code Server from Host from VS Code.
I tried deleting ~/.vscode-server on the Linux host from an SSH session.
I tried Remote-SSH: Kill VS Code Server on Host from VS Code.
I tried Remote-SSH: Kill Local Connection Server for Host from VS Code.
I tried deleting and recreating the host connection details in the local config file from SSH-Remote.
I tried rebooting both local and target hosts.
I tried setting /opt/ as my working dir, then deleting and recreating /opt/t4. I was able to do this, but as soon as I try reconnecting using /opt/t4 as the working dir, VS Code still fails to connect.
I'm... stumped. My suspicion is that there is something corrupt cached Windows-side, but I don't know where to look for that.
Microsoft is aware and working on a fix. There are a variety of workarounds in this thread: https://github.com/microsoft/vscode-remote-release/issues/7324
Thanks to the link from #Mike Barry, I managed to find the local workspace for that target folder and delete it to force it to reinitialize, which cleared the issue.
Deleted C:\Users\me\AppData\Roaming\Code\User\workspaceStorage\[guid]\ and reconnected with no problem.

VScode SSH extension keeps disconnecting after moving to a new location

I recently moved to a different country, but I work remotely and therefore I thought that my workspace wouldn't be interrupted. However, now that I'm trying to connect to my workspace through ssh in vscode, the connection keeps disconnecting. I connect to the workspace through the VPN my workspace provides, and while I can connect to the linux box I work in via ssh, I cannot connect to it through vscode-remote-ssh extension like I did for the past few months. Nothing has changed in terms of settings on my computer. I attached the output vscode provides when I tried to connect below (this is the output from the reconnection attempt but the first connection attempt looks exactly the same).

The connection hangs on [Forwarding server 53048] Got connection 2 for a few seconds before disconnecting me and repeating this message (and asking for password again). I tried removing the .vscode-server file from the linux computer, which is then recreated right away but it still doesn't let me connect. I also tried changing the timeout in the vscode settings but this also did nothing. I am unsure why this would happen after simply physically moving the computer from one place to another but remaining on the same vpn, and why I would still be able to connect with regular ssh but just not through the vscode-remote ssh extension.
You might try ssh manually to the server and delete the remote server folder which makes VSCode download it again from scratch.
This has helped me today:
rm -rf ~/.vscode-server/
rm -rf ~/.vscode-remote/
The suggestion comes from the following discussion: https://github.com/microsoft/vscode-remote-release/issues/2513
You might also wanna check if your new network IP is allowed in the target group of the server.
I had the same exact issue, and for me.
I dont have a resolution but a crappy workaround - reboot the far machine.
im running ubuntu 20.04 and once i rebooted, then i can connect from visual studio and connection stays up, BUT once i close the VSC and restart, then i see this issue again, and again i have to reboot the far machine.
EDIT: later i discovered that stopping the sshd daemon with systemctl start/stop sshd also helps this situation - so no need to reboot
This issue is due to a hard coded 20 second timeout in the protocol between the vscode client and the remote server. This is discussed in detail here: https://github.com/microsoft/vscode-remote-release/issues/7497. No fixes for this yet and will hopefully be fixed soon by making this timeout configurable (to allow overcoming these disconnects).

VS Code Remote SSH Connection not working

Im trying to setup vscode with the remote developement extensions on a second pc. While it works on my main one it doesnt on the second one. Tried reinstalling vscode, extensions and using older versions but nothing works.
When trying to connect it cancels after chosing the os. So I cant even type in the password.
I set it up in the exact same way as with the other pc.
Any ideas?

Depending on the system you are in, when you first try to connect, a vscode-server will be set up and configured on your server.
In linux that can be in /Home/<user>/.vscode-server
If you are on windows, check what that is.
The first solution is to try the extension command: Remote-SSH: kill VS Code Server on Host
Open the command pallet (CTRL + SHIFT + P or COMMAND + SHIFT + P (mac) ).
And type Remote kill :
Then try to connect again! (That will kill the server on the host! Which will make it start again on the next try)
If that doesn't work, and things are still failing:
Delete, rm
Then a good solution that can work is: to connect to your server through terminal (vscode terminal, gnome-terminal, whatever). Then go and remove /Home/<user>/.vscode-server
Try to connect after that. At the attempt the server will be re-installed completely anew, chances are it will work. (I did that and it worked for me, so whatever that was going wrong on the vscode-server: just start all over)
But again: you will lose things, config, meta data, etc. (because you start anew).
Update:
As stated by #natevw in the comments:
I found that removing only the .vscode-server/bin subfolder helped straighten things out and afaict kept my data/settings.
Removing only vscode-server/bin seems to work well, and the config, metadata, etc. remains untouched.
I downgrade Remote-SSH plugin to 0.51.0, rm -rf $HOME/.vscode-server on the remote machine. Connect again, VSCode will download and install a new .vscode-server. Then upgrade Remote-SSH plugin, everything works.
One way worked for me is, by adding this line in the vscode settings (JSON) file.
"remote.SSH.useLocalServer": false
I met the same problem. After I did these steps, it works:
on the remote server:
rm -rf ~/.vscode-server
rm -rf ~/.vscode
On the local VS code:
reinstall remote-ssh
In case all the above fails, here's how I fixed my issue.
First, I was able to SSH into my remote server (Ubuntu 22.04, Raspberry Pi 4, arm64) using a simple bash terminal. So I logged in using my terminal (macOS), and I went to
cd $HOME/.vscode-server/bin/WHATEVER-HASH-YOU-HAVE/
In this directory, there is a file named server.sh. I tried running this script, and I got the following error:
./node: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory
The issue was clear: there was a missing shared library on my system. Either Node.js now requires that or the new version of the SSH-Remote extension; I don't know. I did not spent the time to dig into those specifics.
But to fix that, I simply did:
sudo apt-get install libatomic1
That installed the missing shared library.
After that, I delete $HOME/.vscode-server:
rm -rf $HOME/.vscode-server
and tried again connecting using VSCode. It worked!
Hope this can help someone like me, for whom all other options failed.
Issue: while trying to ssh connect to Linux(remote machine) using vscode.
Solution: remove/delete the bin folder inside .vscode-server and then reconnect to the remote machine
In remote server:
remote_name:~$ rm -rf ~/.vscode-server/bin
*reconnect to remote machine*
It turns out that my fish was a obstacle for vscode server.
Then I tried
chsh -s /bin/bash
And works fine.
I worked adding \\ in the path of the .config
I share the steps
Go to .config settings
select configuration
add double \\
Just deleted old host information from ssh settings file and problem solved.
I had faced this issue when I tried to connect to a Linux server from a windows laptop.
It was using the wrong fingerprint.
It worked for me after removing the line related to that server from $HOME/.ssh/known_hosts
I ran into the same issue, it got fixed when I updated the path of the IdentityFile from 'ssh_key' to '~/.ssh/ssh_key' (the entire path I mean) so that the VS code could recognize it.
Restart remote machine worked for me (after trying all the previous answers with no luck).
Giving you the oldest trick of the book:
restart
It worked for me and I laughed hysterically for exactly 57 seconds. Happy reconnecting to the server my dear Coder!
I could not connect to the server, my issue was the remote server was full
check with the command df -h if the disk is full !
Here is an alternative for Remote SSH, pls check my answer at: https://stackoverflow.com/a/68046111/13089935
TLDR:
We can use a web-based VS Code that is installed on the server directly.

VSCode: Remote - SSH extension - nothing happens when trying to conncet to remote server

I have recently discovered vscode and the remote development extension, and wanting to try it out, but I can't get the damn thing to connect to my development server.
I've installed the both the vscode and vscode insiders packages by downloading the .deb packages manually on my local machine and installed the extension it self by executing this line:
ext install ms-vscode-remote.vscode-remote-extensionpack
Afterwards my pre-configured ssh hosts gets discovered fine and i have key-based auth running and it works fine when connecting to the server from a terminal.
But when I try to connect to the server, by right clicking and selecting one of the two options, only a notification saying "Confirming hostname is reachable" pops up for a second or two and then nothing else happens.
There are no information in the "output" view, other than this line:
remote-ssh#0.42.2
I've checked and confirmed the remote server has the needed prerequisites.
Also i see nothing in the /var/log/audit/audit.log on the remote server when trying to connect, so I dont even think it tries to establish a connection.
What am I missing ?
Local OS: Linux Mint 19 Tara
Remote OS: CentOS 7
I found the issue - "+" signs makes the extension fail: https://github.com/microsoft/vscode-remote-release/issues/612
I have this line in my local .ssh/config
Host *+*
ProxyCommand ssh $(echo %h | sed 's/+[^+]*$//;s/\([^+%%]*\)%%\([^+]*\)$/\2 -l \1/;s/:/ -p /') nc -q0 $(echo %h | sed 's/^.*+//;/:/!s/$/ %p/;s/:/ /')
Which allows me to connect to host b through host a like so:
ssh hosta+hostb
Removing that fixed the issue, and I connect succesfully to a remote host - it simple seems that that vscode dislikes that line.

Failed to parse remote port from server output: bash: no job control in this shell

I am trying to use VSCode - Insiders to run code on a docker container in a remote AWS machine using the Remote - SSH plugin. I have opened a terminal and set up port forwarding like so: ssh -L 2201:localhost:2222 user#host -N -i ~/.ssh/id_rsa. Then in VSCode I try to connect to root#localhost and it starts up, but then gives me an error message:
> Found existing installation...
> Found running server...
>
> bash: no job control in this shell
"install" terminal command done
Received install output: bash: no job control in this shell
Failed to parse remote port from server output: bash: no job control in this shell
I started doing this process a couple days ago and it worked. Yesterday it was in and out a bit, and today it's not working at all. I've tried turning it off and on again, but can't get it to work. In case it's relevant, I am on MacOS with the Mojave OS.
Edit:
Magically, it worked today (the following day) the first time. I would still be interested in knowing how to fix this next time it breaks. In case this helps, here's the output from when it is working:

Edit 2: And now (the following following day) it's not working again.
Edit 3: I have a config file at ~/config. Here are the contents:
Host *
User root
Port 2201
IdentityFile ~/id_rsa
In the specific implementation shown above, you have User root in your config and are logging in with root#localhost, so you have your username twice. Leave the config file as is and just enter localhost in VSCode. This still doesn't solve the instability issue, but it does fix one problem.
I have the same issue when configuring my server. It solved by this issue. After save your config file for remote server, change the remote shell path like this issue, and then connect, you will in.
