Issue Description

I had a working Powershell integrated terminal and debugger just yesterday, using the old version of the Powershell extension.

VS code had a non clean exit (As my system locked up).

This morning I started Visual Studio Code and the integrated terminal doesn’t work. Neither does the debugger. The Powershell extension also updated today.

After the terminal tries to launch it shows:

PowerShell Integrated Console Permissions to the pipe file were not set properly. Expected: 600 Actual: srw------- for file: /tmp/CoreFxPipe_PSES_5b0a428f-e0b7-4e90-b8c8-d0a44966a752

And after a while the terminal closes. Logs below:

the pwsh app seems to work fine in normal bash.

I tried to delete all the pipe like files with the following command: rm /tmp/CoreFxPip* in the hope that it would re-create them correctly, but that didn’t make a difference.

I tried to set the permissions correctly on the file it was complaining about (by running chmod 600 on the file it was complaining about) but that doesn’t seem to work: it seems to re-create the files with incorrect permissions.

Running VSCode as root doesn’t seem to help either (glad it is very loud about warning the user not to do this).

I did find this old issue but this seems to be more windows specific.
