Running sudo mw update on version v0.29.1 produces the following error:
ERROR could not move new binary to location: open /usr/local/bin/mw: text file busy
@Addshore suspects that https://gitlab.wikimedia.org/repos/releng/cli/-/commit/c76ec8ecc708b48e44393dff50c5e166f5a7be61 is to blame.
A workaround to resolve the issue is to run mw update -vv (without sudo!) and then copy the new binary by hand from the location that appears above the line showing the permission error.
Yep, this one is very easy to reproduce.
@hoo do you have thoughts on this as I believe it was your commit?

Jan 2026 stuff, grafana, and updating
Looking back at the commit, I believe it should be fixed with updates from v0.30.0 onwards
If it was fixed, it no longer is. Did a clean install of 0.31.0 today and sudo mw update outputs the same error.
I just did sudo mw update --version v0.31.0 followed by sudo mw update --version v0.32.0 and it seemed to work fine for me?
On what setup were you trying this?
So in the mean time, I've updated another device. - Ubuntu 24.04 laptop, 0.30.0->0.32.0 worked perfectly fine. Ubuntu 26.04 desktop, 0.31.0->0.32.0 failed with the error.
Both using just "sudo mw update"
