[GNC] Build From Source Near Impossible

[crusadeon09]

I'm running Ubuntu, 21.10, Impish Indri.

I downloaded the 4.11 tarball, gnucash-4.11.tar.bz2

I followed these directions:
https://wiki.gnucash.org/wiki/Building
https://wiki.gnucash.org/wiki/Build_Tools
https://wiki.gnucash.org/wiki/Building_On_Linux

I tried changing repositories. I ran "sudo apt update" multiple times. The dependencies for 4.11 simply wouldn't install.

I tried loading them individually, but the names are just slightly off.

Ubuntu sees them differently I guess. https://packages.ubuntu.com/

After a couple of hours of carefully trying to build from source, I give up. Looks like Ubuntu Software Center has 4.11 in a flatpak.

Does anyone have any better instructions? I'd even submit to watching a video at this point.
