Impossible update for dependencies issues with lightdm-webkit2-greeter

---

Today I happen to upgrade the system by yakuake, but I got the following error and can’t update anything.
On pamac the same, at pc switch on there were over 60 updates available.
It’s italian but I suppose very easy to understand.

//:: Aggiornamento del sistema in corso...
risoluzione delle dipendenze in corso...
ricerca dei pacchetti in conflitto in corso...
errore: impossibile eseguire l'operazione richiesta (impossibile soddisfare le dipendenze)
:: lightdm-webkit2-greeter: l'installazione di webkit2gtk (2.12.0-2) interrompe la dipendenza 'webkit2gtk<2.12'
:: lightdm-webkit2-greeter: l'installazione di gtk3 (3.20.2-1) interrompe la dipendenza 'gtk3<3.20'```

Any suggestion?

Same here, but XFCE install. Here’s what I get:

could not satisfy dependencies:
light-locker-settings: requires python-gobject<3.20
lightdm-webkit2-greeter: requires webkit2gtk<2.12
lightdm-webkit2-greeter: requires gtk3<3.20

Any help will be appreciated. And shouldn’t the update manager handle these problems automatically?

Thanks.

@Jeffrey-Needle yes, me on kde

Well it seems lightdm needs somewhere an old package version. But why? Also i dont want to switch to gdm on gnome. Because i did this last week. And because of it my system did not start anymore. Could never get into the loginscreen.

Don’t do this, ldm broke.
If you want to upgrade the other packages before the dependencies are fixed, you can use the --ignore options for the three packages in question.

Same here, antergos gnome, we I get upgrade with pacman -Syu, light-locker just break here.

I have the same pacman error message… any help will be appreciated…

error: failed to prepare transaction (could not satisfy dependencies)
:: light-locker-settings: installing python-gobject (3.20.0-1) breaks dependency ‘python-gobject<3.20’

ditto ^^ will install other packages with --ignore

Same problem here, can’t update anything even on Live DVD.

Edit: Switching to gdm and removing lightdm is a workaround.

same here on antergos gnome

also I have the same problem when trying to update the system

subscribing and awaiting further instructions.

Yeah, i thought it odd to suddenly have 129 packages in my upgrade queue

I have the same problem as well, I’m on gnome using gdm and even when I try to uninstall lightdm (which I should have done before), it crashes too.

Same problem here on XFCE. I unticked all and then installed all the updates that worked and now Package Manager and Update Manager crashes. I have tried through terminal with same issues on remaining updates having dependency issues.

@pedro.a.1smr it lets me install gdm; but systemctl enable gdm crashes
ideas?

same here on antergos gnome

same here with example

Error

Failed to prepare transaction

could not satisfy dependencies:
light-locker-settings: requires python-gobject<3.20
lightdm-webkit2-greeter: requires webkit2gtk<2.12
lightdm-webkit2-greeter: requires gtk3<3.20

**How to fix in layman terms? thanks in advance!

Please add likes(hearts) to the post to avoid the need to make a new response for just confirming it.

I suppose it’s a problem developers can easily solve. Just need to wait and let them know, and @Wyn already did it
