Vscode-remote-release: Failed to parse remote port from server output after the install command

[gcemaj]

I am able to connect to the ssh server through a normal terminal, and i can see the .profile being run from the server in the remote ssh connection inside VScode.

But after that i get the following

"install" terminal command done
Received install output: 
Failed to parse remote port from server output: 

[roytseng-tw]

Execute Remote-SSH: Kill VS Code Server on Host..., and then reconnect.
Above solves my problem.

[Noezor]

Solves it for me too, I tried logging off and on multiple times and it seems that I can't reproduce the bug ... interesting

[gcemaj]

Does not seem to help, i get

Command failed: ssh -T -o ConnectTimeout=15  <ssh_connection> << 'EOSSH'

        kill -9 `ps -ax | grep "remoteExtensionHostAgent.js" | grep -v grep | awk '{print $1}'`
        sleep 3
        # go after the restarted agent
        kill -9 `ps -ax | grep "remoteExtensionHostAgent.js" | grep -v grep | awk '{print $1}'`
        kill -9 `ps -ax | grep "watcherService" | grep -v grep | awk '{print $1}'`

ssh_askpass: exec(/usr/X11R6/bin/ssh-askpass): No such file or directory

Could $SSH_ASKPASS be set to a path that doesn't exist? Not sure what's happening there. Can you try to connect again and attach the full log from the "Remote - SSH" output channel?

[roblourens]

Did you delete some things like at <!!!!! .profile things run !!!!>? It looks like all the output from the install script is gone, can you include that as well?

Would also help if you can check whether /usr/X11R6/bin/ssh-askpass exists and what echo $SSH_ASKPASS gives.

[gcemaj]

i only removed the things that are printed from the .profile running (Company related sensitive things), when i echo ssh_askpass it returns empty

[gcemaj]

/usr/X11R6/bin/ssh-askpass does not exist

[roblourens]

Then it seems like the install script is not running properly. Does your .profile do anything like launch a new shell? It might be doing something that disturbs the install script.

[gcemaj]

it does start a new terminal, commenting that out takes it to wget but it seems to just get hung at that point. Not sure if it is a proxy issue

[roblourens]

Are you using a proxy from the remote machine? Does the environment have http_proxy or https_proxy variables specified?

[gcemaj]

After i specified them i now get the following

> Installation already in progress...

Server installation process already in progress - waiting and retrying 30

It get stuck retrying for a bit then eventually gives up

[roblourens]

Do you only have one remote window open?

It seems to think another installation is already in progress. Maybe something got messed up while failing to install multiple times. Can you try running the "Uninstall vs code server from host" command to clean it up? (Or delete the ~/.vscode-remote folder manually)

[gcemaj]

Killing and retrying led to

[roblourens]

Ok, interesting. Could your remote be missing the CA? Can you try sudo apt-get install ca-certificates?

[gcemaj]

install in the remote or local?

[gcemaj]

I dont think i have sudo privileges in the remote

[gcemaj]

I added the appropriate cert to wget, and finally installed, now i get another issue

[roblourens]

Do you use RemoteCommand in your ssh config? I think that will break us also.

[gcemaj]

I do, anyway around it?

[roblourens]

For now you need to remove that (or clone that ssh config, remove it from one copy, use that copy for vscode). In the future I think we can override it on our end.

[gcemaj]

Removed it and now it gets stuck on

Connected to SSH Host - Please do not close this terminal

[roblourens]

That is supposed to stay there, so are you connected at this point?

[gcemaj]

It says opening remote on the bottom left in the green box, cannot see any files or anything

[roblourens]

Can you share the full log from the "Remote - SSH" output channel now?

Well everything looks correct, but you still can't open files? Can you check for errors in the developer tools console? (Help > Toggle Developer Tools)
