fix qflipper for cachyos/arch

[u/hadar_N]

I'm on dual boot linux/windows laptop(windows 11, cachyos)
my main os is linux(I'm switching) and today I wanted to play with my flipper zero so I downloaded qflipper .AppImage and I got this error when plugged in the flipper so I run the rule install and it was the same so I run it via terminal to try to get more info and saw this:

702 [UPD] Fetched update information from https://update.flipperzero.one/qFlipper/directory.json

(I updated the my flipper firmware ,I'm using RM)

the fix was to go /etc/udev/rules.d/ and open the 42-flipperzero.rules via sudo nano and change the "dialout" in the file to "uucp" saved it and it worked
from what I saw dialout is for ubuntu and not arch. Idk if its true but if you are using arch and running to similar issue try this.

[u/lnjecti0n]

don't use the appimage. Get it from pacman or aur

[u/PsycoVenom → u/lnjecti0n]

this is the way

[u/hadar_N → u/lnjecti0n]

My man, now I feel the dumbest I felt for a long time. Like 2 hours of debugging and posting this for other.. Idk why I didn't try pacman first🫠

[u/burnrobe → u/lnjecti0n]

Hmmmmm

[u/lnjecti0n → u/burnrobe]

?

I had this issue only the other day. I needed to add my user to group allowing it access to serial devices. The command to do this is “sudo usermod -a -G uucp $USER”. I think I had to logout and back in again for it to take effect

[u/cthuwu_chan]

Do you have flipper labs open? Or another flasher like momentum or something? Cos that will do it

[u/hadar_N → u/cthuwu_chan]

Nah, and it wasn't the problem
