Visual Studio Code displays perfectly from a local display on a Ubuntu 20 installation, but just produces a blank white window when run from a remote Ubuntu machine through X-windows. Running code --disable-gpu doesn't help. Other applications such as Firefox, Nautilus, and Eclipse display remotely with no problem.
Any suggestions?
There is an issue for this upstream: https://github.com/microsoft/vscode/issues/110119
Running code --verbose --log debug --disable-gpu prints, among others:
[3440:1116/110926.098706:WARNING:x11_util.cc(1520)] X error received: serial 169, error_code 1 (BadRequest (invalid request code or no such operation)), request_code 130, minor_code 1 (X_ShmAttach)

I don't know much about X, but I would expect X shared memory (shm) to not work via X forwarding, and maybe it's something that vscode currently needs?
It looks like it started in rev 1.66 on my Linux systems.
I uninstalled and installed 1.65 from here:
https://code.visualstudio.com/updates/v1_65
For me the "--disable-extensions --disable-gpu" options worked.
Just install an old version of VS Code.
I use version 1.59.1 and I don't have a white screen anymore when I use sudo.

I had a previous version of Anaconda 2 (working with Python 2.7), which I uninstalled to newly install Anaconda 3 (to work with Python 3.x).
While the previous Anaconda 2 was working fine, the newly installed Anaconda 3 throws the following error:

A quick google search showed that an issue was open about your problems few days ago in github
Fortunately a workaround was posted:
Editing the file: ".../anaconda3//lib/python3.7/site-packages/anaconda_navigator/api/external_apps/vscode.py"
By declaring the variable outside the loop.
Just add the line:
DISTRO_NAME = None
on Line 159 and indent it in line with the if above it (Outside it)
I got a similar experience this morning. But I was able to resolve mine by typing this into my command-line interface(CLI).
conda update anaconda-navigator
I hope this work for you.

On Net::SSH2::Simple,
It has been no longer connected by ssh after update Windows7 to Windows10.
With following error.

My code are

$ssh2->connect( 'xxxx.com', 22 ) ;

Error comes up at "$ssh2->connect" line.
But
This code works fine by using Net::SSH2.
Only Net::SSH2::Simple doesn't work.
To xxxx.com connection is fine. and no username,password mistakes found.
How can I fix that.

Net::SSH2::Simple 0.01 was released Dec 13 2009. At that time Net::SSH2 was at 0.28 (2009-10-24), it is now at 0.70 (2019-3-17).
I got Net::SSH2::Simple to work on Windows10 64bit / Strawberry Perl 5.30.0.1 (64bit) by installing the earlier version 0.58 (2015-12-20) of Net::SSH2 using
cpan install SALVA/Net-SSH2-0.58.tar.gz
Version 0.59_20 (2016-05-11) gives the 'net_ss_timeout: invalid object' error . The change log for version 0.59_01 has this warning
** WARNING: this release includes lots of changes, some
visible, most internal. Regressions are expected. Also,
it introduces some minor backward incompatible changes -
but in those cases, the old behavior was broken or insane
anyway.
I need to read a file myFile.bmp in Octave but it doesn't work.
I have:
Ubuntu 15.04
Ocatve 3.8.2

When I run imread('myFile.bmp', 'Format', 'bmp'), I get the same error.
If you installed everything from the Ubuntu repositories, then you are probably affected by an Ubuntu packaging issue. It was described in comment #6 of Ubuntu bug #1372202.
Since Ubuntu 15.04 has already reached end of life, they probably won't fix it. You can:
upgrade Ubuntu
build Octave from source yourself
I have installed Canopy 1.7.4.3348 (64 bit). My OS is Windows 10 (64 bit). I have the most updated Canopy and Windows 10.
When I tried to update and install any packages in Package Manager, the "Status" would turn out to be "Error", and I got the message:
IOError: [Errno 10038] An operation was attempted on something that is not a socket.
I looked up the Error code on microsoft.com (https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx) and found Microsoft's definition of socket error 10038:
WSAENOTSOCK 10038
Socket operation on nonsocket.
An operation was attempted on something that is not a socket.
Either the socket handle parameter did not reference a valid socket,
or for select, a member of an fd_set was not valid.
I think this error from Canopy may only exist in Windows but not in other OS like Linux. Could anyone please kindly help with this issue? Really appreciate it!!
The detailed messages are as below:

Please file a bug report from the Canopy help menu for Enthought tech support records (and please refer to this SO question in your report).
I don't know what causes this rare error, but it should disappear in Canopy 2.0, which uses a different package manager backend, based on the Enthought Deployment Manager (EDM).
Meanwhile, you can avoid the error by using the command-line package installer, enpkg, from a Canopy Command Prompt. Please see this Knowledge Base article for details: https://support.enthought.com/entries/22415022-Using-enpkg-to-update-Canopy-EPD-packages.
I am using Enthought's Canopy environment on a 64 bit Linux OS. Everything works fine in the Ipython console which is attached with the editor. But when I ipython in the terminal and try to use magic functions, I get the following error.

So, I installed a bare bones iPython shell which is not the one provided by Canopy and tried the same magic functions in there and it works fine.
Have I done something wrong with the installation? Please help
Thanks a lot

This is not a solution, but just an observation. My desktop is MacOS-X and I connect to a Centos machine to run Enthought Canopy both 64 bit. I get the same error message as OP if I ssh from iterm2, but not if I use the Terminal app.
I am not sure what the underlying reason is, but may be someone can verify if a similar situation is true for linux. Interestingly I can use either iterm2 or Terminal on the local canopy without any issues.
Update:
I just noticed that the TERM environment variable in iterm2 was set to "xterm" while the Terminal app was showing "xterm-256color". Issuing the command export TERM="xterm-256color" before running the Canopy ipython in terminal solves the issue for me in iterm2.
Problem reproduction:
$ python -c 'import curses; curses.setupterm()'
Traceback (most recent call last):
File "<string>", line 1, in <module>
_curses.error: setupterm: could not find terminfo database
This irc log gave me the idea that this error was to do with libncursesw.
My Canopy version is 1.0.3.1262.rh5-x86_64. I have installed it to ~/src/canopy.
In ~/src/canopy/appdata/canopy-1.0.3.1262.rh5-x86_64/lib we can see that my canopy install has libncursesw.so.5.7.
My machine (Debian Wheezy 64bit) has libncursesw.so.5.9 (in /lib/x86_64-linux-gnu/libncursesw.so.5.9). I made canopy use this. You can toggle the problem on / off by using LD_PRELOAD and pointing at the .so file.
Solution
Replace libncurses.so.5.7 with libncurses.so.5.9:
CANOPYDIR=$HOME/src/canopy
CANOPYLIBS=$CANOPYDIR/appdata/canopy-1.0.3.1262.rh5-x86_64/lib/
SYSTEMLIBS=/lib/x86_64-linux-gnu
cp $SYSTEMLIBS/libncurses.so.5.9 $CANOPYLIBS
ln -sf $CANOPYLIBS/libncurses.so.5.9 $CANOPYLIBS/libncurses.so.5
It appears that Canopy User Python is not your default. See this article:

Update: Not true here -- instead, see batu's workaround answer.
