Update the debian local package building section

to use aptitude as dep resolver and add backports in given cli examples

---

Migrated from D7039 (view on Phabricator)

Thanks.

--build-dep-resolver=aptitude should only be used when building with an extra-repository which has a non-default priority, that is only when using a -backports suite (so only for the bullseye and buster instructions). It should probably be documented in the list of "useful options" rather than as the default.

You could add a list of useful third party repositories pulled from https://forge.softwareheritage.org/source/swh-jenkins-jobs/browse/master/jobs/templates/debian/gbp-buildpackage.groovy.j2$122-150

Build is green

But does it hurt to use it by default?

good thinking

It can have a different behavior than the actual resolver used for package builds (e.g. not using the first alternative, or handling transitive dependencies differently), so, yes, it'd be much better to only use it when needed.

Ping, what do we do with this diff?

@olasd your last reply is a bit mangled (or is too much quoted?) by the way so i'm not sure i completely get it.

The problem with this last improvement is documenting the correct value to use for the --extra-repository-key for each of them...

specify aptitude is to be used only when needed (sic)
