Does anyone know why is this happening?
I’m looking forward for any info 
P.S. I use Linux Mint 18.3 
What architecture are you running, 64 bit or 32 bit?
Assuming the issue is the architecture, is there something I need to do to get both 32 bit and 64 bit packages? As far as I know, it should work on both…
--arch=x86_64 to install 64-bits. Assuming that by 64-bits you actually mean that and not aarch64 (ARM 64bits)
Sorry, I meant for building, not for installing (I’m the Scribl developer). When I go to see my most recent build, I see three architectures but when I click on some recent builds for other packages I see four. The one I’m missing is i386. Should I be doing something to enable it? (Does anyone still run i386?)
Freedesktop 19.08 isn’t available for i386 arch, so not that’s expected to not have it.
20.08 dropped arm too.
