[Bug]: ppa installs -rc1 when final is avalaible

[shenki]

On Ubuntu 22.04 with the tt ppa enabled and the tenstorrent-dkms package is installed.

The version 2.7.0-rc1 is installed but the repo makes 2.7.0 available, which I assume should take precedence.

The Debian policy manual indicates a prerelease version should be separated by a tilde so it sorts with lower precedence than the final:

https://www.debian.org/doc/debian-policy/ch-controlfields.html#version

One common use of ~ is for upstream pre-releases. For example, 1.0beta1svn1245 sorts earlier than 1.0~beta1, which sorts earlier than 1.0.

So the 2.7.0-rc1 package should probably be called 2.7.0~rc1.

Should RCs be published to the PPA at all? If I have 2.6.0 installed and 2.7.0~rc1 is available, will it automatically upgrade?

That's a policy question. I'd suggest no.

But then again when the newest release version causes various parts of the TT stack to complain about "too new".

If I have 2.6.0 installed and 2.7.0~rc1 is available, will it automatically upgrade?

Yes, as the 7 > 6:

dpkg --compare-versions 2.6.0 gt 2.7.0~rc1 && echo "True" || echo "False"
