Something didn’t work for me in the upgrade (Ubuntu 20.04.3 ):

flox is already the newest version (0.0.7-r76).

The same if I redo the installation after having downloaded the new deb file:

Any clues?

Thanks @gruggiero for the feedback - I think these may be the smoking guns:

I would need to see a detailed set of log messages to be sure what’s going on, but this is something that we definitely haven’t seen before. When I install to a more recent ubuntu host this is what I see:

$ lsb_release -a

Would it be possible to try the installation once more but with the following command?

sudo dpkg --debug=1 -i flox.deb

One last thing (important) - version 0.0.7-r76 has showstopper bugs. Please download the latest (0.0.7-r83) before trying again.

Many thanks for the feedback!

Thank you for the reply, but… no luck:

To help debug the issue, I can add that I had Nix installed before Flox and I uninstalled it following the instruction found on the Nix site.
I don’t know if it’s relevant, given that 0.0.6 seemed to work.

Update: I’ve been able to resolve the issue by removing the package and reinstalling it.

Thank you

Giovanni
