Pinta as a snap

Pinta is a freely licensed cross platform drawing application that emulates the functionality of Paint.NET.

It's source code is available at https://github.com/PintaProject/Pinta/

Build Instructions

For most default Ubuntu environments,

sudo apt update && sudo apt upgrade -y
sudo apt install snapd
sudo snap update
sudo snap install lxd
sudo lxd init --auto
sudo snap install snapcraft --classic

In some scenarios, you may need to reboot once to properly initialise LXD and the rest of the snap environment. You may also have to set up your user with the lxd group; such as in WSL2 for example, with e.g.,

sudo usermod -a -G lxd $USER

Often, followed by another reboot (or just the one - if you did this all in one go).

sudo apt install git
git clone https://github.com/JGCarroll/pinta-snap.git
cd pinta-snap
snapcraft pack --debug --verbose

Snapcraft will automatically set up the entire .NET and Gnome environment and produce the snap with consistent tooling through the LXD backend. You can install your snap with sudo snap install pinta_myVersion_amd64.snap --dangerous, using --dangerous to skip the signature certificate checks. This is fully equivilent to running Pinta from the official snap store except for the requirement to manually connect the removable-media interface on custom versions (sudo snap connect pinta:removable-media).

You may want to consider pointing the snapcraft.yaml file to your own Github forked repository, or instead copying the snap folder in its entireity into the main Pinta repository separately on your local machine, then rewriting the source: to be ./ - i.e, the local folder you're operating upon Pinta directly in.
