Cant use SSH extension

Describe the Bug

I have been using mscode ssh extension for a while but today it does not work anymore so I try to switch cursor ssh extension but run into this error due to lack of permission. Is there anyway to avoid this issue? (I’m a student at a university). I try to use vscode but it does not have the same issue.

Steps to Reproduce

ssh into a university linux server with anysphere ssh extension

Operating System

Linux

Current Cursor Version (Menu → About Cursor → Copy)

Cursor version 1.3.9
SSH version 1.0.23

Does this stop you from using Cursor

Yes - Cursor is unusable

Thanks for reporting this. Your version (1.3.9) is quite outdated compared to the current version (1.5.5), and there have been significant SSH improvements and fixes since then.

Please update to the latest version and retest. If the issue persists after updating, please let us know.

Hi @nmd1411,

Can you also update to the latest version of the Anysphere Remote SSH extension? We made some changes to store the lockfile in the /tmp folder, which shouldn’t have permission issues like this.
