It's easy to forget that what you have in your hands is the best operating system in the world. I've been using Linux since 2005 and I've been following the slow march of the penguin since. I am not a linux zealot. I don't go around trying to convert windows users to linux. I have a few friends I have introduced to this operating system and they also continue to use it everyday.
The latest wonder for me started when Updates offered an upgrade to a new kernel. The kernel is the core of the linux operating system. I accepted. Afterwards, I thought that such an important change to the system should have repercussions. And it does. After downloading the kernel it prompted for a reboot to complete the installation. Reboots are uncommon in the linux update world. When GDM showed up I knew I have a problem with the graphics. Somehow the kernel update broke my Nvidia drivers bindings. Make sense. New kernel needs new instructions to the graphics drivers. When the new kernel could not find it, it went for the fall back, which is Nouveu, I think. So what I need to do is confirm this and grab the appropriate Nvidia graphics drivers, install them. These would need an entirely new how-to post in my mind but in Ubuntu. I opened 'Additional Hardware Drivers' and it shows I don't have the recommended Nvidia driver version. I clicked a button to grab the right version for my card and just gave it privileges to do the installation itself. After 2 minutes it asks permission for a reboot and I did. The next thing I saw is the 3D desktop I am familiar with. So all in all that's 15 minutes to change the core of my operating system plus an unfamiliar tangle with my Nvidia drivers. This is the reason why I love Ubuntu.
I first encountered the problem after a routine update / upgrade of the
system. Well there was a kernel upgrade and I have not checked how many
old kernels are still left for backups in /boot. Apparently, there was
a few and the partition is 85% full. Every software update included a
warning because of the restriction in disk space. Also, zfs could not
create snapshots. It is also full. This is not very clear to me.
Snapshots were suppose to be diff copies so why would it take up a
large space. Most of the snapshots are less than 2MB. Or 0MB.
Another problem that popped up is the constant freezing of Rhythmbox. I
don't know if the config files are corrupted. The CPU cycles from one
to the next. Peaks for 5-6 seconds then on to the next CPU. This forced
me to download Clementine and Audacious. But both applications do not
find the zfs pool or don't show the zfs structure. Why not? My final
solution is to reinstall Rhythmbox via snaps. I re-scanned the music
