Asbru not installing on debian 12
From AcrodusWiki
Asbru-cm does not install well on debian 12 following the instructions on the website/github
Below is an extract of a reddit post explaining the fix.
I have just put Debian 12 Bookworm on my laptop and am happy so far. The only issue I had was I could not install Asbru-cm which I use daily for connecting to 10-12 different servers. Following the Devs instructions for installing doesn't actually work. Everything works until you type "sudo apt install asbru-cm" and the error says it cannot be found. To fix this; Find the file in /etc/apt/sources.list.d which has the repo listed. For me it was asbru-cm-release.list Edit the file and change "bookworm" to "bullseye". Do a sudo apt update and then install normally. It should now work for you.
