[Bug 1766217] Re: software updater presents an empty panel for updating

[Matias N. Goldberg]

I forgot. If after executing those commands now update-manager gets
permanently stuck on "waiting for other software managers to quit"
(which is kept stuck even after removing the locks in all apt places and
closing all software managers), then run:

sudo apt install --reinstall update-manager
