I tested with a fresh installation of Ubuntu 24.04.1 LTS and 24.10 Both using the same configuration on update-manager with Immediately notify.
Only on the LTS release update-manager works as expected and pop up after a couple of seconds when you reboot the system. So there is something wrong with the non-lts releases that prevent update-manager to pop up despite the confguration. You need to execute it manually. Here are some logs when I executed update-manager via cli in 24.10: WARNING:root:can not import unity GI Namespace Dbusmenu not available /usr/lib/python3/dist-packages/uaclient/apt.py:299: Warning: W:Unable to read /var/lib/ubuntu-advantage/apt-esm/etc/apt/apt.conf.d/ - DirectoryExists (2: No such file or directory) apt_pkg.init() /usr/lib/python3/dist-packages/uaclient/apt.py:281: Warning: W:Unable to read /var/lib/ubuntu-advantage/apt-esm/etc/apt/sources.list.d/ - DirectoryExists (2: No such file or directory), W:Unable to read /var/lib/ubuntu-advantage/apt-esm/etc/apt/sources.list - RealFileExists (2: No such file or directory), W:Unable to read /var/lib/ubuntu-advantage/apt-esm/etc/apt/preferences.d/ - DirectoryExists (2: No such file or directory) apt_pkg.init_system() Output from 24.04.1 LTS: WARNING:root:can not import unity GI Namespace Dbusmenu not available WARNING:root:Error loading .desktop file /usr/share/ubuntu/applications/texdoctk.desktop: constructor returned NULL -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2091200 Title: Update Manager notification never pop up.
