Extensions will not work when SSH-ing into a remote Linux machine with a lot of files in home directory

[Proton]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

1. SSH-ing into remote machine
2. Cursor will try to detect if sandbox is available
3. The pilot command cursor-sandbox --blah-blah -- echo 1 will fire a ripgrep process try to scan the entire home directory
4. It timeouts
5. All the extensions will not work because extension host not responding.

We are now removing the cursor-sandbox binary at server side to workaround this, it will come back when there’s an update of the agent. Please fix this.

Steps to Reproduce

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known issue. The team is already aware and working on a fix.

The problem is that the sandbox helper runs ripgrep to scan the directory, and on machines with a lot of files it times out.

Your workaround of deleting cursor-sandbox works.

I’ll keep you posted when the fix is out.
