When i run sudo apt upgrade on my Zorin machine i got this irritating message?
Get more security updates through Ubuntu Pro with 'esm-apps' enabled:
rpm2cpio libmaven3-core-java libgegl-0.4-0 ant python2.7-minimal
libmagickwand-6.q16-6 libgegl-common python2.7 librpmio8 rpm-common librpm8
libhttpclient-java libopenexr24 libsdl2-2.0-0 libsdl2-2.0-0
libmagickcore-6.q16-6 libpython2.7-minimal libpython2.7-stdlib ant-optional
imagemagick-6-common
This is far from normal. Zorin blocks normally those Ubuntu ESM-programs out of their systems. The message you see and get is from Ubuntu Pro extended update program (another extra 5 years full support, on top of the 5 years normal support of the LTS-program).
See your resources list what you have dragged inside Zorin that should not be there.
But, of course, this is a message you can ignore. But as said, you are inside the Ubuntu Pro setup, and for using it you need a SingleSignOn-account AND a Token from Canonical to be a beneficiary of Ubuntu's 10 year full support.
But I doubt really that Zorin 16 can be a part of such a program.
I have 4 Ubuntu Pro's, therefor I really know. lol ... my Zorin is a full upgrade hyper-modern system running on kernel 6.2 and Linux-firmware 20230219xxx , but I have NO SUCH messages at all.
Maybe you ought to try to get 10 years support on Zorin now lol ..... maybe it can work.
No, it's just Ubuntu trying to push their Pro subscription...
The product itself is not bad as it aims to extend the support for another 5 years, totaling to 10 years of support without having to re-install to a newer LTS version.
However, pushing it like this it's just the wrong play here as it confuses people without reason. It also doesn't make a lot of sense to most desktop/laptop users but rather servers where stability is much more important concern.
Better go checking what our dearest friend, the Topic Starter, dragged into his system from Ubuntu instead of using Zorin's repo's.
When I run on a Clean original Repo System I get this on a sudo apt upgrade
As said .... I drag in repo's a lot of times for all reasons to be on top level with the latest kernel out there .... But I delete, of course, such repo's out again before you get one hell of a nasty mix up ......
But I already understand that beginners make those typical mistakes ..... And some blogs do not care for correct information they share.
Check the Software Center and in the settings, look into Repositories (I don't know the exact names so look for something related). There you should have a list of the repositories in use, and should be able to toggle them. You can try to disable anything that comes from Ubuntu, that should get rid of the warning.
For Clarity, Jonte recently followed an alert to "Upgrade" to Ubuntu 22.04. In this action, he added repositories for Ubuntu.
In that thread, we replaced his sources.list. @Jonte have you checked the contents of /etc/apt/sources.list.d?
The git-core-ubuntu - is this something you manually added? if it is not, you should remove each of those.
Please remove all the files labeled as "dist-upgrade".
You should have:
