Describe the Bug

When I connect to Linux from Windows using ‘remote-ssh’, I get this error
How do I fix it?
"
Connection to Cursor server failed: Couldn’t install Cursor Server, install script returned non-zero exit status: Tar failed to extract server contents from cursor-server-44252ffc-55e2-4976-b46b-737d7af357ed.tar.gz

Does this stop you from using Cursor

No - Cursor works, but with this issue

@mylim, does this happen repeatedly? If you haven’t already, could you try the “Reinstall Server” option when the connection fails? This error indicates that the server download failed.

Thanks for your reply.

I already tried ‘reinstall server’, but this happen repeatedly.

In the Output tab, I got this log

Hi @mylim , would you be able to share the full logs? We have seen a few other cases for this where the logs indicated the disk was full, which prevented the .tar from fully extracting.
