Developer of sioyek here.
I have recently made some changes to the build script which should make packaging for debian easier. I have already packaged it myself and it seems to be working well (I built it on Ubuntu 21.10 and tested it on a vanilla Ubuntu 22.04 Beta virtual machine, it might not run on older distros) .

I would prefer if someone else packaged sioyek (mainly because I am a total noob when it comes to packaging) but if no one is interested maybe I can do it myself.
