Hi Simon, > Then – how to actually install that?
You download the file and then you do dpkg -i ~/Downloads/python3-poppler-qt5_0.24.2-3build1_amd64.deb using the path where you downloaded the file. This way you use the file with the older poppler-qt version which still worked (at least on my system) and not the current one you get from > ubuntu@ubuntu:~$ sudo apt install python3-poppler-qt5 I don't remember if I uninstalled the repository version (apt remove) before, but probably not because all the rest depends on it. dpkg installs single deb packages without caring about the dependencies as apt does. But it care about all files in the package and which installed file belongs to the package. Of course, this is less clean as only using the default repository and apt but I'd say less handwired as self-compiled packages or setting PATHs etc. And you can remove it in a clean way again using dpkg if it does not work.
