Doesn't start after installation (Gtk-Message: Failed to load module "canberra-gtk-module") about buttermanager

[egara]

Hi @damian101 and thank you very much for your report.

I'll take a look, because the snap package is a little bit outdated (current version is 1.9). I don't know if it is worth creating a package with the new version or maybe I create a install script because I have found that ButterManager works fine creating a virtual environment with Python.

So I'm going to work on it and I'll keep you inform :)

By the way, on Arch you can install the application via AUR without any problem https://aur.archlinux.org/packages/buttermanager/

Hi @damian101 again!

I've been working on a installation script. Please, do you have time to test it on those environments and tell me if it works?

You have to clone this repository and checkout branch devel:

git checkout devel

Install possible missing dependencies like python3-setuptools and python3-venv packages (maybe the name of these packages are different in those distributions). If you want to activate the integration of your snapshots into GRUB, you should install this tool https://github.com/Antynea/grub-btrfs (in Arch, Manjaro, etc... it is in the official repo via btrfs-grub package)

Then, enter /install directory and execute install.sh

This script should install ButterManager in a virtual environment and create a desktop launcher to execute it.

I will abandon the idea of creating a snap package in favor of python virtual environment because this kind of tools are difficult to isolate using this technology.

I get a very similar output on Arch Linux in VirtualBox:

On my openSUSE Tumbleweed installation in VirtualBox it also doesn't start, but the terminal output is different:

@egara Those steps worked fine on Arch, Ubuntu and openSUSE, thanks!
