There’s a free service by the SUSE folks over at https://openbuildservice.org/, which allows you to set up a package that is then automatically built for all major Linux distributions.
Benefits:
- It creates automatic update repositories for all major Linux distributions.
- It builds from source.
- People won’t have to manually download RPM/DEB files anymore.
- You reach more distros!
- Easier for the users! They can update via their native software apps (such as GNOME Software) if the repo is added to their computer.
- It’s easier to recommend Mailspring to newbies when it can auto-update.
