I recently moved from Debian-basd distributions to RHEEL world. I'm actually using Fedora. At some point, I wanted to install frantz. But I only have two possibilities: .deb and .AppImage and I choosed the .deb. After downloading the .deb file, I use alien to transform it to .rpm.

1. Install alien (if not)

sudo dnf install alien

2. transform .deb to .rpm
