ptyHost was unable to resolve shell environment Error - visual-studio-code

So I've been having a lot of issues with VS Code Remote-SSH. I just started using it in September, previously using Atom, and this month I've been running into a ton of issues. I wound up uninstalling VS Code twice to try and resolve it, as well as delete the .vscode-server folder in the home directory on my linux machine.
Now, I can't even use VS Code to ssh into my environment. It keeps giving this error. This is from the .vscode-server/.log file.

I was using a Bash shell. However, I got it to work, actually. I had to reboot the server to do it. Not exactly sure why. For future reference, I ran
sudo systemctl reboot
and that fixed the problem.

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.

VS Code Remote-SSH: The vscode server failed to start SSH

I'm trying to connect to a server via remote-ssh extension for Visual Studio Code, however, I'm getting the following error:
The vscode server failed to start SSH
Everything is fine on the server-side, and the connection to this host worked fine for a while.
Any suggestions to re-access the server via remote-ssh extension?
After a while, I found a solution that can be useful to others.
In VS Code press:
CTRL + SHIFT + P
Type or select the option:
Remote-SSH: kill VS Code Server on Host...
Select the host name:
And after this procedure, try connecting again to the host.
That worked for me.
In my case it was ssh plugin issue. I updated remote ssh plugin then it worked
wrong proxy setting may cause problem.
If Remote-SSH: kill VS Code Server on Host command not work for you, open settings and clear proxy setting and retry.
Everything is fine on the server-side, and the connection to this host worked fine for a while.
In case it is a simple intermittent network issue, VSCode 1.70 (July 2022) will retry the connection for you (up to 5 times)
See issue 127565 and PR 156444
Retry up to 5 times the initial authority resolving and also retry up to 5 times the initial connection
When connecting to a remote, if the initial connection fails, we will give up. The idea was that retrying would be useless, since the initial setup might have failed.
But it is possible that perhaps it was an intermittent network error.
This is available in VSCode insiders today.
Update the Remote ssh
check file groups belongs to same group if you manually copied .vscode-server
Remote-SSH: kill VS Code Server on Host...
Didn't work for me, so I tried the other option:
Remote-SSH: Uninstall VS Code Server from Host...
It took a bit more time but worked for me!

bash: powershell: command not found

For a node project I will have to work on a remote server and for that I will use filzilla for file transfer and ssh for console.
I use Visual Studio Code, I installed a remote ssh extension,
I did the hostname and user configurations as well as secretkey,
because before that I had another error The process tried to write to a nonexistent pipe ,
which I finally solved but now after I start ssh and log in with the password in cmd from Visual Studio Code, I get this error bash: powershell: command not found.
I tried one day to search the internet for that error.
https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_server_configuration?WT.mc_id=-blog-scottha
https://learn.microsoft.com/en-us/windows/wsl/troubleshooting
I've talked to people who have more experience but within the time limit my advice could be, but I still couldn't solve the error, either it's something from windows or ssh or I don't know.
You are the first time I try to do this in general I used heroku or aws that had some facilities.
I changed host machine in the settings JSON file windows to linux
When you got the option to Select Linux, Windows or Mac did you make sure that you know exactly the type of server you are connecting to. Bcs if you choose the wrong one this error gets thrown.

Manage to connect through the terminal, but not through the remote explorer

I am coming from notepad, and am learning how to work with VS Code.
I am now trying to access my online repertory on the webserver.
I followed up the guide here: https://code.visualstudio.com/docs/remote/ssh
I did manage to access my server through the terminal window.
(ssh user#domain + password).
When connecting, this shows in the log:
"Linux infong-eu27 4.4.246-icpu-061 #2 SMP Thu Nov 26 10:58:41 UTC 2020 x86_64"
This tells me that it is working on Linux.
If I type "Ls", I can see my folders and navigate among them.
So far, so good!
Second phase: Connecting through the remote explorer.
Step 1:
I configured the ssh with the same credentials I used with the terminal.
Step 2:
I am opening the remote explorer, I can see my server's name. I right click on it and select "connect".
Step 3:
I am then asking to choose the system. I am picking Linux as shown earlier when connecting through the terminal.
Step 4: I am entering the same password I used before to connect in the terminal.
Step 5: Infinite loading, or a very long one till I get 2 notifications / errors:
Could not fetch remote environment
Failed to connect to the remote extension host (error time limit..)
That being said, it also says in the bottom left corner, in the "remote window", that I am connected. This does not seems right.
Any chance someone could help?
I am frustrated because it connects in 1s using the terminal, but not in the remote explorer.
UPDATE:
I found this article on medium that paraphrases the official documentation.
https://medium.com/#sujaypillai/connect-to-your-remote-servers-from-visual-studio-code-eb5a5875e348
I managed, through Git bash, to create a ssh pair key, and managed to copy one on my server.
I then followed the instructions on how to set it up on VS Code successfully!
Now, when I try to connect, I am asked for my key pass:
But, when I do: super long loading, and the same error message.
When I looked on my server with a sftp software, I see that VS did manage to connect as files were installed in a VS folder it created:
This is reported in issue 4415 (no answer) and issue 4204
The last one includes:
This might be caused by our new automatic port forwarding feature which scans the remote OS for available ports in order to forward them locally (microsoft/vscode#112843)
This is fixed by PR 113342, for the next 1.54 Feb. 2021 release. That bug is about setting remote.autoForwardPorts to false and... still seeing VSCode auto-forward ports!
Check on your server (while VSCode attempts to connect) if:
the CPU is high
if there are any services running on public port on said server
I solved a similar issue by following the error logs from the remote ssh extension. I had to install libatomic1 on the remote server with
sudo apt-get install libatomic1

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.
