So it should be the some other components which don't make Android a 'real' Linux according to some definition.
Personally I agree, that the Linux kernel makes a system a Linux system. However, the choice of a specific C library is important as it ensures some kind of binary compatibility between distributions, i.e. download a generic 'GNU/Linux' binary and run it is possible.
As far as I understand the comment on Wikipedia, Android can be seen as a Linux distribution, but not as a GNU/Linux distribution which we commonly understand as 'real' Linux.
Android is a Linux distribution according to the Linux Foundation, Google's open-source chief Chris DiBona, and several journalists. Others, such as Google engineer Patrick Brady, say that Android is not Linux in the traditional Unix-like Linux distribution sense; Android does not include the GNU C Library (it uses Bionic as an alternative C library) and some other components typically found in Linux distributions.
Back then 13 cm, 15 cm, 17 cm and 21 cm artillery cannons were in use, so the shells were not necessarily significantly smaller. However, modern artillery shells surely are more complex involving microelectronics or even rocket propulsion and the use of modern explosives makes the 'boom' also bigger.
Yes, that matches what I've found too. The goats climb into argan trees to eat the fruits. However, farmers place goats in the trees for tourists and force them to stay there all day, which is bad for the goats, as they are subjected to the sun and heat, as well as for the trees, as the hooves damage the bark.

AfaIk that's not entirely true, e.g. Debian is changing the system time from 32 bit integer to 64 bit. Thus I assume other distros do this as well. However, this does not help for industrial or IOT devices running deprecated Unix / Linux derivatives.
My recommendation would be to copy your entire home directory with rsync -a onto another (external) drive, as you anyway don't want to modify your partitions without having a backup.
Then boot into a live distribution and open a partition editor, delete the home partition (the data on it will be lost), expand the root partition (/) onto the entire disk. Finally copy the backup back into the home folder using rsync -a
If sudo apt -f install doesn't work properly, you can create an apt-cache folder on, e.g. your home partition, assuming this is the one with sufficient amounts of free storage.
Concerning the cloud workspace, it would be possible, that the IT services of the Danish regions (or of the whole state) run centralised clouds (Nextcloud, Moodle, ...).
AFAIK, there might an error in the first part, at least in Europe, where you have 3 Phase AC coming to your home, the neutral line connects to ground in the main breaker box, not the other way round. For US, this shouldn't be different.
I just installed the Flatpak version of Inkscape (the first GTK application, that came into my mind, where it makes sense to have the latest version installed) and the Breeze dark theme works for me.

I use Debian btw. ;-)
