[arunc1985]

This is a linux level issue, not VSCode. Check if remote VMs have proper scp configured? Are you able to scp manually?

[naveace]

Hi @arunc1985 , thank you so much for your help! Both the server I am connecting to and my local machine have scp configured correctly. I can SCP the files manually, but not from file:///var/folders/bg/wpb6hx715v1dqhv8nbpkxnqr0000gn/T/vscode_server_1650494141537 as that path is invalid on MacOS. Instead I have to cd into /var/folders/bg/wpb6hx715v1dqhv8nbpkxnqr0000gn/T/vscode_server_1650494141537 Furthermore even though I do SCP it manually, this usually only fixes the issue for one session (if at all). Often times after doing this, a tar process on the server will start trying to unzip the server installation only to immediately die and then just hang.

Following up on this issue

[roblourens]

Might work without "remote.SSH.localServerDownload": always, if that's possible for you.

/bin/sh: scp: No such file or directory

Let me know if this is still an issue, this is probably complaining about the server or the flag file, do either of those not actually exist?

[naveace]

Hey @roblourens , thanks so much for the follow up! Sadly I require that options as the servers I am connecting to often don't have a strong enough connection to download directly. Both the flag and the server file exist on my machine (I manually scp them over each time)

[18:35:42.384] "Copy server to host" terminal command done

Does that exact command from that exact directory (without file:, we are just logging the URI format) work? What command are you using?

[naveace]

Hey @roblourens , yes. I use that exact command from that exact cwd to copy it over (removing the file:// beforehand).

[roblourens]

Strange- the actual command we run looks like /bin/sh -c "scp ..." Could you try that with the logged scp command just to see whether it works any differently? It shouldn't, but I don't know why else the same command works when run manually.

[naveace]

Hey Rob! Indeed when I run the exact command with /bin/sh -c scp ... it gives me the output posted above:

usage: scp [-346ABCpqrTv] [-c cipher] [-F ssh_config] [-i identity_file]
            [-J destination] [-l limit] [-o ssh_option] [-P port]
            [-S program] source ... target

However if I add the ", /bin/sh -c "scp ..." then it works as intended. It appears for some reason my installation is missing the "

[roblourens]

Hm, we don't actually quote it in our implementation but we pass it to an API in a way that should be equivalent to quoting it. Not sure why it works for everyone else but not you, we should do some investigation to figure out whether we should be quoting the shell arg that we pass to the terminal API.

[naveace]

Got it; thanks so much for looking into it and let me know if I can provide any additional information about my setup that will be helpful.

[karcaw]

Im am seeing this issue as well, but cannot seem to figure out why the scp fails

[guomk]

Same issue on my side. Previously it worked well but suddenly started to fail this morning. Do we have an update on this?

Noticing this issue again in vscode version 1.88
