[I have absolutely no idea how focal-updates got removed, but following the dup question directions, I just added this line deb http://br.archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse to sources.list and ran sudo apt-get update and libsdl2-dev became installable properly thru synaptic]
here is the problem
$ sudo apt install libsdl2-dev
libsdl2-dev : Depends: libasound2-dev but it is not going to be installed
$ sudo apt install libasound2-dev
libasound2-dev : Depends: libasound2 (= 1.2.2-2.1)
$ sudo apt install libasound2
libasound2 is already the newest version (1.2.2-2.1ubuntu2).
how to install it now? is it really impossible!?
If it is impossible, I was thinking on downloading every libsdl2-dev dependency tree, extract the packages and just point the compiler to such folder, I think it could work.
But that is also a huge problem, because I would have to grab each package individually, as I cant find a way to just ask them to be downloaded w/o installing :(
Any better idea? Any easier way to do a thing that should be simple?
I cant compile the SDL2 project locally now, I cant test it, ahhh...
Is the only other/simple option to grab the sources and compile them from official site?
