I have both qt5-wayland and qt6-wayland installed. Is qt5-wayland still necessary?
If you have an application that uses Qt5, it is necessary.
You distro is capable to remove packages when they have no program needing them.
Use apt autoremove or equivalent for your distro to clean things once in a while.
Don’t remove things on your own if you don’t know what you do and don’t want to create problems for yourself. The package manager is smarter than you to handle packages. This isn’t something a user is supposed to worry about.
You can find out which packages depends on qt5-wayland but that’s distro specific.
Thank you for the reply.
I note that (on my system) qt5-wayland is needed by: guiaddons5 kwayland-integration kwayland5 plasma5-integration.
Applications needing qt6-wayland are, among others: kguiaddons kwayland plasma-integration.
So I was thinking that perhaps these qt6-wayland dependencies offer the same functionalities as the ones listed under qt5-wayland. If so, I should not need qt5-wayland anymore, since I have no 3rd party apps in need of it?
Then what those are bused by ? They are themselves libraries.
They offer the same functionality but for qt5 code which is binary incompatible with qt6.
If so, I should not need qt5-wayland anymore, since I have no 3rd party apps in need of it?
Are you sure you have no apps that depend on those ?
If that’s the case autoremove should clean those up.
I am using Arch Linux, so no autoremove. However, I am sure no apps other than the ones I listed are using qt5-wayland. If I understand you correctly, the system itself (KDE, Plasma, Wayland) doesn’t need qt5-wayland as long as qt6-wayland is installed.
Thanks, I am familiar with Arch. Seems we are talking past each other.
