Hello everyone,
I also confirm that there is an issue with the Software Updater GUI (/usr/bin/update-manager) in Zorin OS 18, which is never periodically displayed automatically when updates (even security updates) are available, even if everything is correctly configured in "Software & Updates" parameters.
There are already several different topics regarding this issue :
- Software updater not automatically displaying new updates Zorin 18
- https://www.reddit.com/r/zorinos/comments/1ovcoev/updates_anyone_is_not_getting_updates/
- https://www.reddit.com/r/zorinos/comments/1pj2oo9/zorin_18_unattended_updates_and_update/
- In Zorin Linux 18 Pro the Software&Updates GUI app will not run
This problem did not occur in Zorin OS 17.3.
Currently, the simplest workaround is to add "/usr/bin/update-manager" in the "Startup Applications", in order to trigger the Software Updater at every session startup, but it is just a workaround, the Zorin team should investigate this problem.
As for me, I've already reported this issue via the official feedback section : Send Feedback - Zorin OS
