## Description Charmcraft is failing to pack within a Github runner using `--destructive-mode`. The specific charm needs to install `apt` packages in the host system and it's failing because of permissions. We thought that getting rid of the `--destructive-mode` would solve the permissions issue, but fails as well. The only solution that is working for us is running the `pack` command using `sudo` alongside `--destructive-mode`, not the best practice, but the only one that works for us. After reading this [article](https://discourse.charmhub.io/t/building-your-charms-with-github-actions/4992) I've run manually all the commands by SSHing into the runner and I was able to pack it without `--destructive-mode` (with LXD). But whenever I do the same from the action (Javascript action with `exec` calls), it gets stuck and never comes back. Maybe that's related to running the command as another user using `sg` or running an `exec` call from Javascript. ## `Charmcraft.yaml` ```yaml type: "charm" bases: - build-on: - name: "ubuntu"
