Fedora 34 was released a few weeks ago, and now I took some time to update my work machine to the new release. Here are some tips I found interesting:

How to upgrade via command line

Upgrades can be applied via CLI with

sudo dnf upgrade -y && \
sudo dnf system-upgrade download --refresh --releasever=34 --nogpgcheck  --allowerasing -y && \
sudo dnf system-upgrade reboot -y

Note that this will take care of removing unneeded or conflicting RPMs. It can be a little too eager removing packages, so you can inspect later what was done via dnf history list and dnf history info X.

Fixing the horizontal dock

I'm a fan of the old way the dock was handled (vertically on the left). Moving the mouse to the top left corner to activate the 'Activities' button, then moving the mouse to the bottom to choose the right application I want to launch seems like a lot of mouse travel.

Fortunately there are extensions that fix that behaviour and revert to the old one.

This extension needs to be used in conjunction to Dash-to-dock, which is available from the linked repo, or installed from RPM with dnf install gnome-shell-extension-dash-to-dock .

Ta-da!

... and that was it for me. Pretty uneventful upgrade as everything seems to work ok.

Happy hacking!
