I'm not new to Linux, having used various distros, including OpenSUSE, Ubuntu, Fedora and Linux Mint, off and on for the past 12 years or so; however, I am brand new to running Linux apps on a Chromebook under Crostini, having only discovered this capability a couple of days ago. I've definitely been brushing up on my terminal skills, having to install apps from the command line instead of an app store. The latter is something Google definitely needs to develop before they bring Crostini out of beta, but I digress.
It took a little effort to get LibreOffice installed but I still can't get my printers configured. I found a set of scripts to accomplish it but it's giving me a bunch of dependency issues. It appears I have Python 3.9 installed but CUPS is looking for version 3.8. I'm not sure how to resolve this.
In an attempt to come up with an easier way to install software in the absence of a dedicated Crostini app store, I installed the Discover app store but so far have found it to be next to useless. None of the apps I've installed from it seem to work. Firefox and Thunderbird don't appear under my Linux Apps, although I can launch them from within Discover, and while GIMP's icon appears under my Linux Apps, it won't launch. A dialog box comes up saying that while I have the latest version of GIMP installed, it was built against Little CMS 2.2 and my Chromebook has Little CMS 2.9.
Anybody know how to fix this stuff?
