[Bug] Update process leaves stale lock file, blocking subsequent updates

[graham-u]

Bug Description Every time I try to update I get the same error, last 3 updates:

trying to run: claude update

Result: Current version: 2.0.65 Checking for updates... Another process is currently updating Claude. Please try again in a moment.

Then I have to find the lock files and delete them in ~/.local/state/claude/locks

• Platform: darwin
• Terminal: iTerm.app
• Version: 2.0.65

My issue is updating, not installing. And on Mac, not linux

[kenryu42]

Same issue on Mac. Was trying to update to 2.0.65. Thanks @graham-u for the delete lock files tip!

[UdiMizrachi]

had the same issue on Ubuntu also, once when trying to update to 2.0.65 and again when trying to update to 2.0.68 had to delete .local/state/claude/locks/*.lock files to resolve , tried also reboot before that - didn`t resolved until .lock files were deleted

This worked for me. Thanks.

Happened to me, ran ~/.local/share/claude/versions/2.0.74 and rm -rf ~/.local/state/claude/locks/2.0.74.lock and then claude update and the update worked.
