This has been yet another great week for Linux news, releases, and whatnot. We have another critical Sudo vulnerability patched in all major distros, a new major Firefox release to update to with better privacy features, a new Nvidia graphics driver with support for Linux kernel 5.10 LTS, and new Linux kernel vulnerabilities to patch in our Ubuntu computers. On top of that, I’m taking a first look at the brand-new MX Linux Fluxbox edition and the Ubuntu 20.10 (Groovy Gorilla) operating system on the Raspberry Pi 4 computer. Of course, I’m also covering all the latest distro and software updates, so check them all out in the 9to5Linux Weekly Roundup for January 31st, 2021, below!
