Unused Linux image-generic on ubuntu 21.10

gb flag

I find that there are three different Linux-images installed on my system.

usr@ubuntu2004:~$  dpkg -l | grep "linux-image*"
ii  linux-image-5.13.0-20-generic                 5.13.0-20.20                          amd64        Signed kernel image generic
ii  linux-image-5.13.0-21-generic                 5.13.0-21.21                          amd64        Signed kernel image generic
ii  linux-image-generic                           5.13.0.21.32                          amd64        Generic Linux kernel image

My system specs are;

Operating System: Ubuntu 21.10
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
Kernel Version: 5.13.0-21-generic (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i5-8250U CPU @ 1.60GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620

If I understand correctly, Linux-image 5.13.0.21.32 is not in use. I wonder what it is doing on my system? Is it required? Can I remove it without breaking my system?

Ubuntu has normally two kernels installed: the current and a previous. The latter is needed in case there is a problem with booting with the latest one.

You have two images: 5.13.0-21.21 and 5.13.0-20.20.

linux-image-generic is a meta package that depends on the latest Ubuntu kernel image. If you remove it, you won't get kernel updates.

So everything is correct.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
