Man I hate it when my Kirita gets all crusty.
Ugg; this, unfortunately, borked my system.
Initially I got the āPlease install all available updates for your release before upgrading.ā message when I clicked on the upgrade notification.
Weird. The dependencies should be fulfilled, and the environment sane, before the user is notified, butā¦whatever.
I went into Discover and applied the system update group and rebooted. Upon next boot the notification popped up again. This time the āupgradeā ran without complaint or fanfare.
However, the next reboot left me with a black screen. 
I downloaded my home directory, made a bootable USB from the latest User Edition ISO, reinstalled, rebooted, ran updates, rebooted, and attempted the 24.04 upgrade on a fresh out-of-the-box install.
This time the āupgradeā was different; each of the steps were enumerated. Again the āupgradeā ran without error, but with the benefit of confirmation of success (supposedly).
The next reboot dropped me to my UEFI password, which is NOT normal. I found that there was no boot entry for KDE Neon (Secure Boot is, and always has been, disabled).
I had wasted enough time on this so I re-reinstalled Neon 6.2. Iāll wait and re-retry the upgrade to 24.04 at a later point.
And due to these problems KDE should switch to rolling release model , openSUSE slowroll is the best of both worlds , It gives montly major updates and security updates throughout the month but the flaw is it is not Ubuntu so people will lose access to various PPA and .deb files support which makes Ubuntu based distros more supported by 3rd parties than something like openSUSE

Ha-ha, what a stupid 
.
If you press Ctrl+C while upgrading a distro, you will abort it and your distro will be broken and you wonāt be able to run the upgrade again 
because the upgrade python script is broken now
/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeGettext.py:33: SyntaxWarning: invalid escape sequence '\%'
arguments_in_message = message.count("%") - message.count("\%")
/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeGettext.py:34: SyntaxWarning: invalid escape sequence '\%'
arguments_in_translation = translated.count("%") - translated.count("\%")
OMG
What kind of dumb idiot came up with this in 2024
How-to manually launch neon dist-upgrade?
the terminal way
For how long will jammy continue to be supported? I am busy right now and donāt want to do a release migration yet, but I want to keep my packages up-to-date.
Right from Wikipedia about Ubuntu:
As you can see of Jammy, extended desktop and server support end in the middle of 2027. And the extended security maintenance is even longer (past 2032). So, there is tons of time.
Iām not rushing to upgrade either just for the fact that the upgrading process has been rather rocky from the looks of it.
In fact, I made a backup of my OS drive and upgraded it as a test in a virtual machine (after restoring the image I made to the virtual machine). Despite it upgraded, the GUI tool crashed and I had to manually configure packages and then clean up the old packages.
Iāll probably give it another try in a month personally.
Make a backup before doing anything regarding upgrading! You may be sorry otherwise.
Advice, for the future, keep your OS drive small and make another partition to have your home folder on. Make a full disk backup. And store your files on other drives so that it doesnāt take long to backup and restore your OS. But also backup your files on an external drive as well; drives do fail after all.
I personally never trust the operating system when it comes to my files (mainly because the drive the OS is on is always under the most stress). So, I keep them on a separate drive for that reason (along with backing them up on external ones as well).
Anyway, if something happens to the OS during an upgrade, you just need to restore the OS partition of the drive; leaving the home folder intact (or vice versa should something be accidentally removed from the home folder you could restore that instead; or both partitions). Meanwhile, your files on the other drives remain untouched.
I recommend Rescuezilla for full drive backups. Itās a fork of Clonezilla, but has a GUI to easily make backups.
Also, is it safe to overwrite the configuration files while upgrading? Thatās what I did.
I also got this:
Here is the output:
After rebooting and removing LAPACKE and Spectacle it seems to be fine.
I had this issue when I took a copy of my system and put it in a virtual machine. Because I wanted to test to see how the upgrade would take. This is where the upgrade tool crashed.
In this case, you just need run sudo dpkg --configure -a to configure the remaining packages.
Then just run sudo apt autoremove to clean up any unnecessary packages.
Then your system should be fine after the upgrade. I upgraded all of my systems running KDE Neon today. All things considered, it seems like the upgrade was smooth enough to make the transition to the newer Ubuntu 24.04 base.
PS: I keep telling people this; always backup your system before upgrading! Rescuezilla; use it!
