get up, clean up, don’t give up the files (and the termites)

As I was trying early July to upgrade my current version of Ubuntu (after a year of procrastination) to 24.04 (Noble Numbat!), I found there was no enough space on the partition element where the upgrade was to take place. I thus started removing superfluous applications, until removing a clock induced a massive removal of attached files and required reinstalling the missing theme to log in…
1924 sudo apt-get autoremove 1926 sudo apt-get autoclean 1929 sudo du -d 1 -h 1932 shutdown -r now 1934 apt-get install sddm-theme-breeze 1935 sudo apt-get install sddm-theme-breeze 1936 sudo apt-get install --reinstall plasma-desktop 1941 logout 1943 sudo apt list --installed | grep -i linux-image 1946 sudo du -h /var/lib/snapd/snaps 1947 sudo journalctl --disk-usage 1957 sudo apt remove linux-image-5.4.0-97-generic 1961 sudo apt remove linux-image-5.4.0-71-generic
I then realised older versions of the Linux kernel were store on that space and eating most of that precious space (as numbats are eating termites) and removed most of these versions with no visible damage. The same issue (of the missing breeze theme preventing regular login) occurred once again at the upgrade stage, with the same patch.

Even though most people are now aware of the Shellshock security problem on the bash shell, here is a test to check whether your Unix system is at risk:
[sourcecode language=”bash” gutter=”false”]
env x='() { :;}; echo vulnerable’ bash -c ‘echo hello’
[/sourcecode]
if the prompt returns vulnerable, it means the system is vulnerable and needs to be upgraded with the proper security patch… For instance running
[sourcecode language=”bash” gutter=”false”]
sudo apt-get update && sudo apt-get install –only-upgrade bash
[/sourcecode]
for Debian/Ubuntu versions. Check Apple support page for Apple OS.
If it ain’t broken, don’t fix it!

I tend to minimise the instances when I have to change of Linux version on my computer (a Macbook Pro Santa Rosa), for this always is a traumatic event with potential consequences on my work, and therefore I had postponed leaving Kubuntu 7.10 (Gutsy Gibbon) in a typical procrastinating attitude, i.e. till something stopped working! This happened yesterday with a failed attempt at upgrading R and I thus moved to Kubuntu 8.04 (Hardy Heron), using the upgrade option rather than re-installing the whole thing from scratch. The only manual steps were to change xorg.conf to accomodate the touchpad and to install madwif to get access to the wireless—the most frustrating part was finding a valid address! (Upgrading Ubuntu means that each intermediate version needs to be installed before moving to the next.) Now that everything works nicely (including suspend and hibernate, and my earlier heating problem seems to be resolved as well!), I am wondering whether or not I should move to the next version of Kubuntu 8.10 (Intrepid Ibex, terrible tee-shirt!) or even to the most recent Kubuntu 9.04 (Jaunty Jackalope, terrible name: jaundiced jackal, jovial jabiru, jocular jellyfish, or jittery jaguar would have sounded way better! The next animal in the list of releases is a koala, although karmic would hardly have been my adjective of choice)… As an aside about this future release, an interesting announcement is that Ubuntu 9.10 would support cloud computing.
