I am quite new to Linux and Debian. I really like the fact that apt can be used to upgrade both software and system packages at the same time. Much better than Windows.
However, I am baffled about one thing. I currently have kernel version 5.10.0-19-amd64. When I run sudo apt-get update and sudo apt-get upgrade, apt suggests me an upgrade to the SAME kernel version. I already once accepted that upgrade and it messed up my touchpad settings - KDE Plasma kept forgetting my touchpad settings and when I tried to change those settings, it kept reverting them back. I had this same problem with Debian 10 and it drove me crazy. I've put that package on hold but still it would be nice to know why this is happening.
