Software updater doesn't honour selected updates

Software updater in the system tray tells me there are 7000-odd updates to install (this Tumbleweed, so as expected).
I click ‘install updates’, and I get a warning about a failed package dependency.
So, I hunt down the package with the dependency and uncheck it. The ‘select all packages’ checkbox goes grey (so it has registered my change to the selection).
I click ‘install updates’ again, and I get the same warning about the same failed package dependency.
Forever…

(This is clearly a bug, but I can’t report it via Bugzilla because the log-in process through idp-portal seems to be goosed - it keeps telling me there’s already an account for an (old log-in email address that I’ve deleted), despite removing cookies - and once I log-in with the right credentials, there’s no link back to to bugzilla…)

The best way to update Tumbleweed is

zypper dup

Yup - that’s as may be, but there’s still a fairly critical bug in the updater widget.

It is the updater applet from KDE Plasma. So you should report it upstream…

I disabled the updater widget in the system tray and go with my own updater:

karl@erlangen:~> cat Schreibtisch/Dist-Upgrade.desktop 
[Desktop Entry]
Comment[en_GB]=

Comment[de_DE]=
Exec=/usr/bin/systemctl start dup.service
GenericName[en_GB]=

karl@erlangen:~>  

The widget starts systemd service dup:

 erlangen:~ # systemctl cat dup.service 
# /etc/systemd/system/dup.service

Description=Distribution Upgrade 

[Service]
ExecStartPre=/usr/bin/nm-online
