Debian package versions inconvenient for distribution upgrades

tinuzz commented 4 years ago

Program: Authoritative, Recursor
Issue type: Feature request

Short description

Debian package versions in repo.powerdns.com for the recursor currently take the form of '4.3.0-1pdns.stretch' and '4.3.0-1pdns.buster'. For the auth server, it's similar.

In Dpkg, '4.3.0-1pdns.stretch' is actually a higher version than '4.3.0-1pdns.buster', which means that when upgrading the distribution from Stretch to Buster, it takes a downgrade action in Apt to install the right version of the package.

My suggestion is to add something like 'deb9' and 'deb10' to the version strings, instead of (or maybe in addition to) the strings 'stretch' and 'buster'.

Usecase

Upgrade a server that has PowerDNS installed from Debian Stretch to Buster.

Depending on the exact installed package set, this also leads to an upgrade problem for "curl":

Well, the fact that you haven't 'sidegraded' PowerDNS prevents curl from being upgraded, it's not the version string of the PowerDNS package that prevents curl from being upgraded. But yes, PowerDNS should be upgradeable without this kind of effort.
