From FAQ:
What should I know about Linux support?
The new Epic Games Launcher runs natively on Linux, but many games are Windows-only builds and may need a compatibility layer. Check each game’s Linux compatibility before installing.
We support Ubuntu 22.04 LTS or newer, Fedora 43 or newer, and Debian 12 or newer. Other distributions may work but aren’t officially tested or supported.
Use the Send feedback button in the launcher to report issues.

Also epic is rebuilding Easy Anti-Cheat for Linux (EAC Linux v2) to deliver near-Windows-level protection using signed kernels, Secure Boot, TPM 2.0, and other existing Linux security features starting with a Fortnite, so more multiplayer games can finally support the platform without enabling widespread cheating.
Checking if you run the default kernel is way better than shipping rootkit to everyone.
It's almost too good to be true.
The worse part is requiring secure boot, as if I wanted to have a dual kernel set up (my nornal, unsigned, I own my hardware and do what I want with it kernel and my locked down, M$ approved and signed, we own you epic games kernel) I can't just switch between them with a bootloader like rEFInd or GRUB, I have to go and enable secure boot each time in the BIOS. You don't need secure boot to play Fortnite on Windows. This is worse somehow.
Secure boot + tpm is probably a developer toggle the same way linux is now. It would be stupid to make linux users jump through more hoops than windows users, we are basically all people who gave up trying to jump through hoops for tech companies. HOWEVER, we are talking about epic games
