Hello,
I’ve installed guix on a virtual machine.
I’m trying to add the nvidia config from the nonguix readme.
I’ve run guix pull and setup the nonguix channel in channels.scm.
When I run sudo guix reconfigure config.scm I get the error:
guix system: error: profile contains conflicting entries for upower
guix system: error: first entry: upower:1.90.2 /gnu/store/...-upower-1.90.2
guix system: error: second entry: upower:1.90.2 /gnu/store/...-upower-1.90.2
guix system: error: ... propagated from gnome@46.7
hint: Try upgrading both 'upower' and 'gnome', or remove one of them from the profile.
I’ve tried guix upgrade upower gnome, but that just gives
guix upgrade: warning: nothing to do
I’ve tried guix install gnome upower, which installs them in my profile, but re-running guix system reconfigure config.scm gives the same error.
I tried reverting the changes for adding the nvidia nonguix config, and the command sudo guix reconfigure config.scm completes sucessfully. So I assume something’s wrong with the gnome imports that are introduced as part of the nvidia config.
I think the issue might be that the nonguix channel packages are interfering or are not in sync with the guix channel.
I tried pinning guix and nonguix channels to v1.4.0 commits, and now I get the same error but for slightly different packages.
guix system: error: profile contains conflicting entries for gtk+
guix system: error: first entry: gtk+@3.24.30 /gnu/store/3hfbyphf96riviip19cqap6hnmai6q8m-gtk+-3.24.30
guix system: error: ... propagated from network-manager-applet@1.28.0
guix system: error: second entry: gtk+@3.24.30 /gnu/store/gsyxsri4k6nncw0wb75gxff0zg2nc9xv-gtk+-3.24.30
guix system: error: ... propagated from gnome-online-accounts@3.45.2
guix system: error: ... propagated from gnome@42.4
hint: Try upgrading both `network-manager-applet' and `gnome', or remove one of them from the profile.
Is there a way I can work out which commits to use for both channels that will work?
I also tried the commits used in daviwil’s dofiles channels.scm, with no luck and the same error, with different packages.
