vscode: Extension installation hangs on remote host when the remote has network connectivity issues

• VS Code Version: 1.75.0
• OS Version: Windows_NT x64 10.0.19045
• Remote OS Version: Remote SUSE Linux Enterprise Server 15 SP3

I work on a remote Linux server and I try to install an extension. It hangs just like on my previous ticket with the same problem https://github.com/microsoft/vscode/issues/164796. The title is not representative of the actual problem in the ticket anymore, since sandy081 changed it.

First I’ve tried with my old .vscode-server and at least https://github.com/microsoft/vscode/issues/164796 with the current title seems to be fixed since I cannot spam “Update” anymore. Unfortunately install and update as such is still broken by just hanging there and never finishing. This means: “Install” button changes to “Installing” and never changes again. No more progress updates from the terminal.

Installation of complex extension I tried again and deleted my remote .vscode-server folder, opened my remote workspace and clicked “Install” on the Python extension and this is the trace log output:

Installation of simple extension From my past and current experience I found that the issue is mostly limited to complex extensions that have one or more dependencies like C++ or Python. Meanwhile simpler extensions usually (always?) install successfully, but while still showing many errors on the way there:

I also found multiple other open issues about installing extensions that fail in weird ways. Please get to the bottom of it since the only thing we can do in the meantime is to copy or just manually install every update and sometimes also update the extensions.json manually.

If I can do anything to debug this issue please tell me!
