Cannot mix incompatible Qt library x with this library y

UltraBlack · 15 May 2022 19:29

Hey there,
I'm facing some trouble with a few Qt programs (bauh, Raven Reader): When I try to launch them, they crash with the error Cannot mix incompatible Qt library x with this library y If e.g. x is 5.15.3 and y is 5.15.4, the crash is understandable, though if I then downgrade qt5-base to 5.15.3 the error now shows x being 5.15.4 and y being 5.15.3 - HUH? Like what?
Can someone explain this to me?
Thanks!

Ah crap - Qt5 5.15.4 its on repos, and after update, Qt apps doesnt work (I added the artix mirrors because of archlinux-tweak-tool

This is weird

UltraBlack · 15 May 2022 19:46

Restored a backup. I wish garuda update had an option to ignore packages, if it forces me to update anyways.

I literally can't update my system, even after disabling the mirror, because of the dumb sweet theme dependency problem

SGS · 15 May 2022 20:03

If you use

garuda-update

it will do it for you automatically.

:: sweet-theme-full-git and sweet-kde-git are in conflict (sweet-kde). Remove sweet-kde-git? [y/N] y
:: sweet-theme-full-git and sweet-cursor-theme-git are in conflict. Remove sweet-cursor-theme-git? [y/N] y
:: sweet-theme-full-git and kvantum-theme-sweet-git are in conflict. Remove kvantum-theme-sweet-git? [y/N] y
:: sweet-theme-full-git and sweet-gtk-theme-dark are in conflict. Remove sweet-gtk-theme-dark? [y/N] y
:: sweet-theme-full-git and plasma5-theme-sweet-git are in conflict. Remove plasma5-theme-sweet-git? [y/N] y

I did read that forum post a while ago. The dumb part is, that garuda-update forces me to install stuff that inevitably breaks my system, but updating without it also does the same thing, apparently.
I solved the dependency problem with pacman -Sdd sweet-theme-full-git (all the garuda tools apart from the assistant are broken on wayfire anyways. Cool stuf, but hella useless like this) to avoid garuda update. That worked, but apparently garuda-update is required for the new grub-silent (Why tho, I want to see grub, I need it for backups) package to install properly...

I am stuck, I have no clue what the right approach is now.

dr460nf1r3 · 15 May 2022 20:22

Actually we might add a switch for packages to ignore @TNE

SGS · 15 May 2022 20:22

You mean Rdd, right?

UltraBlack · 15 May 2022 20:23

Sdd, the packages were merged into one I think

aaaa, one of these 200 packages breaks sddm so it crashes upon boot. I don't know which it is, but it's probably qt related. this is dumb - See https://termbin.com/slplo

SGS · 15 May 2022 20:29

Help me, IDK this Sdd

https://wiki.archlinux.de/title/Pacman#Pacman-Datenbank

Not in the S list

TNE · 15 May 2022 22:21

@UltraBlack I highly encourage you to follow the following steps:

Restore a snapshot from before your funny little -Sdd adventure, which I’m sureeee also totally didn’t involve doing --overwrite at all
Reboot
Delete the snapshot restore btrfs subvolume, you don’t want it to start using up space over time because it doesn’t get automatically deleted.
Add the package you want to ignore to /etc/pacman.conf’s ignore statement
garuda-update

But then, you should be asking yourself if ignoring package updates is really a solution to your problem in the first place.

Take a look at the pacman man page, paying special attention to the following linked section: pacman man page

I meannnn I guess? But I don’t really want to encourage this kinda stuff, because this just results in a partial upgrade.

wongs · 16 May 2022 10:23

This may or may not apply to you, maybe your issue was indeed the sweet themes, and you may in any case need to reinstall the distro or restore a snapshot.

However, but I'm just wondering if the original reason for that "incompatible Qt library" error message was something much simpler, in view of the fact that you appear from your posts to favour ignoring some upgrades.

I had a similar message appear in my Manjaro XFCE install when I tried to open qmplay2 (AUR).

Originally I thought it had something to do with qmplay2 being built on a newer qt5 base and maybe Manjaro Stable was still on an older qt version in between its 3-weekly updates (since I had no problems in Artix or Anarchy), but checking all the dependencies showed it was not the case. Once I realised that Manjaro Settings Manager (native to Manjaro) was also affected, I knew that could not be the reason.

Turns out the simple cause of it was that qt5-styleplugins [used in my old Manjaro install to theme/set the environment for qt apps] was no longer maintained by Arch/Manjaro and had been pushed to AUR, and Manjaro was theming Qt apps on their gtk desktops a different way going forward. I had been too lazy to update it from AUR or remove it, since I mistakenly thought it was no longer needed and not in use.

Once I updated it, all the Qt applications had no issues opening again.

So the question is: Are you ignoring the update of some package, AUR or otherwise (how about from the artix repo you enabled)? Do you perhaps have a setup where theming of Qt apps is based on an older qt base?

PS. I would also advise against partial upgrades.

UltraBlack · 16 May 2022 12:41

I didn’t actually. Sdd ignores package dependencies, not conflicts. I am not stupid.

I tried that, but the update still causes the same behavior. I am gonna update once more, but this time I am gonna use LY, and see if it’s just a problem with SDDM

EDIT: Did a reboot, and tried LY, again the error from above. Seems like sddm crashed because of that.

Yeah, this is definitely the case. Something breaks so badly, that nothing works afterwards.

I’m not ignoring any package from artix currently. As I said, I am only using it for the archlinux-tweak-tool (which refuses to open because I am on wayland, bruh)

I have no idea, how I would check if I am using non-qt5 or qt6 theming, but I had qt5-styleplugins installed already. I tried uninstalling that, but it didn’t help at all.

I am gonna try clearing the package cache, because that might be breaking the updates, even without the artix mirrors, and then update again. Wish me luck I guess.

EDIT 2: No wonder nothing is helping, qt5-base is also borked in the official repos:

EDIT3: Success! (Kinda) - I added qt5* to the ignorepkg list and this allowed me to update without any problems. I will keep it like this for a while and just check on qt5 from time to time, but until this is resolved or I run into other issues, I am gonna keep it like this. I know that this is a very bad and not recommended solution, but it’s my best bet at the moment, to finally allow more updates again. I will keep this thread open in case something else happens (If I mark this as solved, the bot will lock it way sooner than otherwise - Tell me if I should just open a new thread, or if that will be ignored, because of the partial update problem)
Just to round this up, here is my optinion on QT: I hate it. it refuses to theme properly on non-big-DEs, it’s clunky, unreliable on wayland (Please rewrite your tools in gtk, I literally can’t open them, apart from garuda-assistant). Sadly a lot of programs depend on it, so this is a bad situation. If I could, I would just completely remove it from my system.
Thanks to all of you, who tried to help me. I will probably be back in a while

UltraBlack · 28 May 2022 21:16

Noticed that qt5-base got updated to 146 finally so I updated that and had no problems at all
