From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Grub-btrfs troubles (beehaw.org)

Hello all, I'm having some network problems on my server (Ubuntu Lunar Lobster Server Edition), namely my plex port is no longer reachable from outside the network despite it being port forwarded and allowed through ufw. A few days ago I used airvpn's eddie gui program, and it completely wrecked my network. Caused it to be completely cut off from internet when disabled, even with the killswitch function off.

I rolled back to a snapshot I'd made earlier using snapper and grub-btrfs and thought the problem was solved. But while I regained the ability to access the internet, it still seems to have messed something up. I can't seem to get my kernel upgraded. I have 6.2.0-25 installed, but I can only boot into 6.2.0-24, even when I apt removed the older kernel. I believe this is what is causing my networking issues, though even if it's not I'd need a solution so as to be able to keep my kernel updated.

I'm at a bit of a loss at this point and am wondering if I've dug myself in too deep with grub-btrfs. I'm contemplating getting a fresh image on there and sticking to manual use of snapper.

Any help would be much appreciated, thanks.
