Disable dnfdragora-updater in Fedora

Disable dnfdragora-updater in Fedora

dnfdragora-updater is responsible to look for new package updates to your system. By default it is configured to do so every 180 minutes.

Fedora 30, Virtualbox and libxcrypt

Fedora 30, Virtualbox and libxcrypt

Comments 0 Comment

It is a never ending story. New dist release, new problems with Virtualbox.

What is the current problem with a Fedora 30 guest on a Windows host and Virtualbox 6.0.8? Well, the guest additions won’t work, especially vboxadd.service refuses to start.

After asking my search engine of choice it revealed the libxcrypt to be the culprit. There are some changes mentioned at https://fedoraproject.org/wiki/Releases/30/ChangeSet and it is referenced at https://forums.virtualbox.org/viewtopic.php?f=3&t=92953.

Solution:

Install the libxcrypt-compat package and the vboxadd.service will start again, problem fixed.

In full screen mode this works really well.

But suddenly I had huge problems with my left mouse button. In some windows it worked, in others it didn’t and vice versa. After trying random things, it worked for some time, then stopped again. Or didn’t work at all.

The system was actually unusable any more.

It took some time until I realized this strange behaviour was caused by the latest kernel update to 4.17

As soon as it was clear I just had to use the old 4.16 kernel the next steps where easy.
