Cannot install Alexandria on Ubuntu 20.04.4 LTS

[campanile]

The procedure exits with an exit code 1. I also installed Ruby with ruby-full How can I solve the problem?

here is what I obtain:

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

Can you try just installing the glib2 gem? If that fails, please file an issue at the ruby-gnome project: https://github.com/ruby-gnome/ruby-gnome/issues

Maybe trying sudo apt install build-essential patch ruby-dev zlib1g-dev liblzma-dev

[mvz]

Closing this since the problem seems to be in installing glib2 and there's no response on that from the original submitter.
