...why can't it be a bit quicker to get kernel updates
I know, this isn't how Ubuntu rolls, and Zorin rolls even slower.
I personally prefer the Debian/Ubuntu eco-system to Fedora's ecosystem. I prefer AppArmor to SELinux and .deb/apt to .rpm/dnf. But - brand new Zorin 18 is 6.14.x kernel, vs my Nobara box's 6.17.x. ~6 months "behind" isn't too bad, but that's soon after release of 18. Zorin 17.3, today, is on 6.8 which is from mid-2024! That's just TOO out of date for my tastes - i do play games and sometimes my hardware is not 2+ years old.
So with that in mind, i would like to try running more recent kernels, mesa etc. What do people who like Zorin, but like it a bit more edgy do?... oooh, that's a cool idea: ZorinOS Edge...
I'll experiment on the VM. I reckon it'll go well except maybe when Zorin 19 arrives and the upgrade process doesn't account for my meddling and something goes kaput
Note: Using ppa-purge with Ubuntu derivatives needs to include -d <based_on_name> to work safely. For example, Linux Mint 20 is based on Ubuntu Focal, so that would make it:
sudo ppa-purge -d focal ppa:kisak/kisak-mesa
"
So as Zorin is a ubuntu derivate you would use the -d jammy (for Zorin 17) or -d noble (for Zorin 18) flag.
