!?!? I managed to do this:
I’m on Bluefin.
I downloaded and ran:
./Logic-2.4.29-linux-x64.AppImage --appimage-extract
Then I started my Ubuntu distrobox, I think this will download and create it, if you don’t already have it:
distrobox enter ubuntu
Then I did this (because it complained earlier about this lib when I tried it):
sudo apt update
sudo apt install libnss3
Then I changed into the folder where the application was extracted, and ran it.
cd squashfs
./Logic
And it ran.
