The software I use for work is being supplied only in deb package (also exe, rpm, but no ppa) , but I am Manjaro user. Manjaro AUR has got the software, but it is badly outdated, so I think AppImage comes very handly in this situation.
Please, can you recommend me a step by step tutorial of making AppImage from *deb file.
if the original AUR file is build from the deb package, you may be able to simply update the PKGBUILD file with the updated deb file info and build your package to install the software you need. building arch packages from deb files isn’t that hard. You can also use debtap to build an arch package directly from the deb file
