Public bug reported:
The sbuild package is part of the Ubuntu main archive [1]. It can be used to
build packages reproducibly using chroots. This is especially useful to build
packages for Debian and multiple Ubuntu releases on a single system.
According to sbuild.conf(5), sbuild defaults to `dose3` for its
`BD_UNINSTALLABLE_EXPLAINER` configuration [2]. It is used for explaining build
dependency installation failures.
If such failure happen, sbuild tries to install the `dose-distcheck` binary
package, built from the `dose3` source package. This currently fails when
working on a chroot that only has Ubuntu `main` enabled.
The reason is that the `dose3` source package is not part of main, but part of
universe [3].
This means that if a uninstallable error happens while working on a pure `main`
Ubuntu chroot happens, we need to create a new chroot with `universe` enabled
to debug the error. This takes a lot of time and investigation to figure out
that `dose3` is not available in main.
A solution would be to patch the sbuild package to not use
`dose3` by default but `apt` instead or if `dose-distcheck` is not found.
However, it seems that `dose3` is the
default for a good reason. I believe that it is more advanced than the `apt`
explainer. Doing this would reduce the quality of the tooling we use in
Ubuntu compared to Debian.
Another solution would be to create a MIR for `dose3`, but it B-D on ocaml
and on many ocaml libraries. Getting all of ocaml into main may be undesirable.
