I want to make it easier for anybody who wants to install Joplin on Fedora using dnf install joplin to find the right commands. I'm new to Fedora so I was unsure if I should use AppImage or flatpak or compile on my own, and there is no RPM in the repo's release assets, only DEB. The alien compilation from that deb to rpm doesn't work in case anybody wonders.
Joplin's the most often used application for me so I want it to have the best performance. Fortunately, there's a COPR package and the current version (3.3.13) is the same as the official on Github, so I hope the owner keeps it up to date. I guess the startup time is slightly faster, other than that it's hard to notice a difference but I believe RPM is always faster.
There are instructions there, also for OpenSUSE. On Fedora it boils down to
Prep the repository . . .
sudo dnf install -y dnf-plugins-core sudo dnf copr enable taw/joplinInstall . . .
sudo dnf install -y joplin
Hope it helps anyone.
