I actually wanted to upgrade to Fedora 43 today, which is technically possible, but there was a problem with the MySQL database. I am using a manually installed, older version of MySQL (probably the 9.2 repo version, which was a mistake). That was a tip from a contact on LinkedIn back then. The installation worked without any problems. But now, when downloading the files, I got a message saying that the server could not be found.

Yesterday evening, there was a disruption on the Microsoft servers (MS Azure), and at first I thought that was the cause of the problem.

The message that curl (a command that can download files, similar to wget) gave me

Here in the directory:

https://repo.mysql.com/yum/mysql-8.4-community/fc

When I looked in the MySQL repository, I noticed that the folder for fc43 (Fedora 43) was missing. That was the first sign that MySQL had changed its packaging strategy. Before spending hours troubleshooting, I decided to install 42 and then see what was wrong with 43.

I have now found the problem. There is no longer a repo file for MySQL in Fedora 43; instead, it is part of Fedora in general. The message is dated 7 June 2025. Sometimes you should focus more on the release notes and less on your private life. I don’t know if it would have made the news about Linux, either.

So I’ll be able to switch to Fedora 43 soon. I only read about it once the upgrade to Fedora 42 was already underway.

At the beginning, I still had done a

dnf autoremove

This uninstalls programmes that are no longer needed. This freed up 874 MB of space on my device.

The command for uploading the files

sudo dnf system-upgrade download --releasever=42

In any case, I then started downloading the 4 GB of files, which was enough space in the root directory. I had already experienced a situation where there wasn’t enough space. Since then, I have been meticulous about ensuring that there is always enough space available.

After the download, I was asked about OpenPGP. I could confirm it.

With

sudo dnf5 offline reboot

The installation began.

I don’t know how long it took this time because I was busy doing other things on my notebook. But I felt that it went much faster than the previous upgrades.
