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.

Still pretty new to Linux, I'm on Ubuntu Studio 24.04 LTS and had some issues with updates through the updater with errors and so I did sudo apt update/upgrade instead. Something went wrong and had errors, and after a reboot I had no internet access, Ethernet or WiFi, and no options to connect to anything. Running sudo lshw -c network showed unclaimed networks.

In case anyone has a similar issue, I fixed it by:

  1. Reboot, spam shift to get into grub
  2. Advanced options
  3. Recovery mode for the lower number kernel
  4. Enable networking
  5. Fix broken packages

My question is about number 3. There were 4 kernel options, 2 normal with a recovery for each (I can't remember the specifics but one had 37 and the other 36). I selected recovery 36 as it was the older kernel. Is that amount of options (2 for each kernel) normal or can I create more? Like 37, 36, 35, 34, etc.

I was in panic mode since this PC is for work, and thought it might be nice to have more older kernel options if possible. I've also learned my lesson and am currently running Timeshift.

Interesting thanks. I'll look into it more.
