When I attempt to install GNOME Adwaita dark mode the following results appear.

goose@goose-HP-EliteBook-840-G2:~$ sudo apt install adwaita-qt
[sudo] password for goose: 
E: Malformed entry 1 in sources file /etc/apt/sources.list.d/third-party.sources (URI parse)
E: The list of sources could not be read.

BTW I have tried several versions of VLC and all fail to read the adwaita in the preferences menu on VLC.

Has anybody encountered this problem before?

So I'll throw in my two-cents. Was this an upgrade from 24.04 or a fresh install ? Have you checked your Software & Updates app under Other Software ? That is where most all PPA's will be found. Follow that PPA to the website so you can update the repository. You may need to delete the PPA in question before adding the "new" repo. (BTW - Make sure that the Canonical Partners box is checked. ) For accessing the file itself, I use root in my file manager to modify files. So with Nautilus, go to /etc/apt/ --and open-- /sources.list.d/ as ROOT. Now you can delete or modify the offending file. (You may need to install nautilus-admin with sudo apt-get install nautilus-admin ...) Nautilus-admin enables root access to folder and files through file manager. NOTE: I always use Synaptic Package Manager to manage all software. It's the first thing I do after an install: sudo apt-get install synaptic --- I highly recommend installing it.
