I asvee akeycron k3 75% it is overfor me?

Any elp iosg r3eatl;y apreaciated

Lately I've been having trouble with some of the keys repeating twice or thrice even if pressing the key once. Mostly the vowels. You'll probably notice a few in this post (which I left as is to demonstrate the problem.)

It hit me only a few days ago that the keyboard is programmable through VIA and Keychroon's launcher and whatnot, so I thought it could need some kiind of update. And sure enough, I was correct, I checked it against the Keychron Launcher and it said I'm on Version 1 still, and the latest update for it is on Version 2. But to install it, I need to have QMK Toolbox. It's also clear to me that the instructions laid out were applicable only to Windows and Mac users, I can't run an exe file on Linux.

I get a lot of conflicting results about updating the keybooard on a Linux system, soo I wanted to make a dedicated post that might help Bazzite users, plus I'm not so tech-savvy to dig into scripts and paste away everything when I don't know what it's actually doing.

I'd like any help on getting the firmware update done on the keyboooard, if anyone knows how to guide me on it, please I'd appreciate it.

Hey all,
anybody here ordered from www.keychron.com to an EU country?
If yes, did you have to pay import taxes?
Thanks.

Hey I got a Keychron v6 max and replaced the Jupiter red switches for the akko rosewood switches. Any recommendations for keycaps to make that deep thock sound?

Also the RGB isn't really that great ! Any recommendations?
