update failed

Error message

update failed

What it means

Failure path in CliAppService.update(): the package-manager update command ran but returned a non-zero exit code. The CliAppError carries the truncated stderr/stdout of the failed run (or the literal 'update failed' when the process produced no output) and status 500; the install state is left unchanged.

Solutions

1. Run the update command manually to surface the real error
2. Check registry reachability and authentication, then retry
