• Verified that there were no strange errors with

su - zextras -c 'zmcontrol status'

• stopped Carbonio

su - zextras -c "zmcontrol stop"

• Started the Ubuntu release upgrade (from server and not SSH)

do-release-upgrade

• I answered yes to automatically restart services
• I kept my config for sudoers, samba and sshd (no questions about config for boot or grub.conf)
• When upgrading I didn't read messages about software-properties tool for focal in /etc/apt/sources.list.d/ files
• I answered y when I got questions about "continue" that informed me about packages that should me removed (I had 8 packages to remove first time the installer wanted to continue and later 82 obsolete packages to remove)
• When asked to reboot I answered y
• After reboot I change file /etc/apt/sources.list.d/zextras.list (installer had commented out the line but changed focal to jammy) to

deb https://repo.zextras.io/release/ubuntu jammy main

• Then did similar with cat /etc/apt/sources.list.d/pgdg.list (installer had just commented out the line):

deb https://apt.postgresql.org/pub/repos/apt jammy-pgdg main

• As I had the file /etc/apt/trusted.gpg I copied it to /etc/apt/trusted.gpg.d/

cp /etc/apt/trusted.gpg /etc/apt/trusted.gpg.d/

• Then I updated the repositories and I got no errors.

apt update

• Now time to upgrade Carbonio and PostGreSQL

apt upgrade

• I said Y to use prometheus.yml package version. I also let the upgrade restart some services as it was linked to old libraries. And after the upgrade I ran a pending-setups

pending-setups -a

• Just to be sure (maybe not needed)

/opt/zextras/libexec/zmfixperms

• Carbonio is not in a good state right now. So I stopped Carbonio and rebooted Ubuntu.

su - zextras -c "zmcontrol stop"

init 6

• Verified the logs and services and everything looked ok

su - zextras -c 'zmcontrol status'

systemctl list-units carbonio*
systemctl status carbonio*

Thanks everyone!

I will give it a try. Still have some time. 🙂

Hi,

We appreciate your effort to highlight a valid situation and possible workarounds until we have any official words. But at the same time we would appreciate it much more if you elaborate the discussion in the forum thread/post (including the step details) while redirecting users to external platforms, while well-intended, can limit engagement and dilute the collaborative spirit of our forum. We encourage our users to discuss/explain an issues in details as much as possible in the forum. Keeping everything here ensures that knowledge is preserved, accessible, and benefits the entire community in the long run.

We deeply respect all platforms, but for the growth of our community, we encourage discussions to stay within this space. By doing so, we foster a thriving, solution-oriented environment where ideas, workarounds, and collaboration can flourish.

Again, we are thankful to our users for their contribution but we would expect them to respect our forum guidelines for the betterment of our community.🙏

Please feel free to read the guidelines here:

I will try to do Ubuntu upgrade this weekend or the next.

For migration the are probably several guides but I will probably use cmbackup together with Z2C if needed.

These looks like a lot of work for a simple guy like me

fix PostGreSQL repository
copy trusted.gpg
fixing other focal repositories
fixing permissions
fixing logrotate
reinstall unnecessary packages

Isn't there any script to do these automatically for us?

It looks very simple, but @anahuac has a more detailed guide, but it is one year old: https://www.anahuac.eu/carbonio-upgrade-ubuntu-from-20-04-to-22-04/

So is it so strait forward to update Ubuntu from 20.04 to 22.04 as the Carbonio guide or should you stop Carbonio before do-release-upgrade and other cleanup tasks, e.g.

• fix PostGreSQL repository
• copy trusted.gpg
• fixing other focal repositories
• fixing permissions
• fixing logrotate
• reinstall unnecessary packages

Anyone that have followed the Carbonio guide for OS upgrade to Ubuntu 22.04 with Carbonio 25.03? Success or failure stories that you can share?

Thanks

My Carbonio CE is running on Ubuntu 20.04.6 LTS and as you all know, the support for this OS is going to end on May 2025. The OS keep telling me to perform a do-release-upgrade to 22.04.5 LTS

Now is there anyone who has done if before? If I do it, what would be the challenges? Kindly point me to a conversation where I can learn what I need to do before performing the uppgrade.
