Comment 0 for bug 1912718

Before introducing bug https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1910556 that bug didn't exist -- I can toggle these checkboxes and they will checked by default.

After fix of https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1910556 checkboxes for "Remove old kernels" are not checked anymore by default and I can't check them. If I run update-manager from console, nothing logged.

Screenshot and video when I trying to click on checkboxes attached.
