Cursor doesn't execute the command of agent and stuck

lixiangwuxian · January 15, 2026, 6:24am

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After updated to 2.3.35, I found that the agent can no longer run any command, but only hangs there. Cancel the running command does not make agent leave the hang. I have to click the stop button to end the conversation.

Steps to Reproduce

Ask LLM to execute any command, and it will just hang there.

Expected Behavior

Commands should be executed normally

Screenshots / Screen Recordings

Operating System

Linux

Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.3.35
VSCode Version: 1.105.1

Node.js: 22.20.0
V8: 13.8.258.32-electron.0
OS: Linux x64 6.17.9-1-default

Additional Information

Any command will cause the hang.

Does this stop you from using Cursor

Yes - Cursor is unusable

Tried the AppImage and rpm package. They both have the problem.

Hey, thanks for the report. The dialog shows up, but the command hangs after you confirm. This is a known issue with the terminal on Linux in 2.x, might be a regression.

Try Legacy Terminal:

Settings > Cursor Settings > Features > Legacy Terminal, turn it on
Restart Cursor
Try running the command via the agent again

Alternatively, turn on auto-apply (Settings > search for “Auto-run”). This will skip the confirmation step.

If that doesn’t help, please send the Request ID (chat menu > Copy Request ID) and console logs (Ctrl + Shift + P > Developer: Toggle Developer Tools > Console tab).

Legacy Terminal does not hang now. However, it just says failed for each command runs.
I have already enabled allow list for auto run. Certainly ls is in the list.

Seems it’s trying to start zsh. But I only use fish&bash and never installed zsh.

After manually installed zsh, the command run works now.

However, I never asked for zsh in rules, memories or prompts.

deanrie · January 15, 2026, 9:14am

Thanks for confirming. I see the issue got resolved after installing zsh. This looks like a bug. Cursor shouldn’t require zsh if you’re using fish or bash.

The logs show that Cursor is trying to launch zsh regardless of the system SHELL variable. This is a regression in 2.3.35.

I’ll pass this to the team to fix. Ideally, Cursor should automatically detect available shells or use the one set in SHELL.

Thanks for the detailed logs, they really helped us find the root cause.

MahdiNazemi-NVIDIA · January 27, 2026, 5:31am

Thanks for sharing this issue with the team. 2.4.21 is still suffering from this issue.
