Which release was this run on? Is it 24.04LTS?

[fcarreno-git]

Yes, Kubuntu 24.04.1 LTS x86_64

[anbe42]

This should already be fixed in Git by #188.

[pkoutoupis]

I will cut a new release/label in the coming weeks but just llike @anbe42 states, it should be on master. @fcarreno-git please try master.

[fcarreno-git]

Hi Petros,
I've tried new master version and it worked fine !
Thanks and congratulations for your work.
