Out of disk space error (with plenty of space)?

I’m getting an “out of disk space” error when trying to install software in a Fedora qube.

The file explorer shows plenty of disk space.

Increasing the qube size and rebooting doesn’t change anything.

Making a new qube with a larger initial size didn’t fix it either.

Anyone know what would cause these symptoms, and the fix?

Did you increase the “System storage max size” (In the template/standalone) ? And I assume you are trying to install with DNF?

df -h
in a terminal. Is there anything showing 100%? Maybe root is full, but the user partition has free space.

Are you using a template?

Which size did you increase?
