Well, you have to decide yourself if you want/need those applications still using Qt4…
I’m not sure at the moment why zypper wants to remove wine and audacity as well, those shouldn’t need Qt4.
Probably because of the “-u” (–clean-deps) switch, unrelated to libqt4.
As long as the system boots and I can access zypper, I’ll be content. ;-]
Sure, neither the “system” nor zypper need Qt4.
Even YaST is Qt5 based since openSUSE 13.2…
Is there a way to install lmms with zypper and prefer Qt5?
If you create an RPM package, you can install it with zypper (or rpm, doesn’t matter).
If you want to prevent “zypper dup” replacing it again with the standard version, you need to lock/taboo it or add a repo with the Qt5 version (which you could create yourself on OBS)
Is there an easy way to taboo all of the unwanted packages (e.g. amarok)
that would be reinstalled via zypper dup?
“zypper al amarok” or “Taboo” in YaST.
Or “uninstall” the pattern that recommends it.
