Bug Description

[impact]

prometheus in Focal is missing dependencies and thus is unbuildable.

adding/upgrading packages may affect other packages.

prometheus autopkgtests will continue to fail for the lifetime of Focal due to missing runtime dependencies:

Thanks for taking your time to report this issue and help making Ubuntu better.

I get the same error message when attempting to run `sudo apt build-dep prometheus` on Ubuntu 20.04. It does indeed look like some of the required dependencies are newer than what is available in the archive. Makes me wonder how this was built in the first place...

Changed in prometheus (Ubuntu):

it was copied over from Debian, where the deps are (or were) available, but it appears not all the deps were pulled over at the needed versions.

Yes, the sourcce was copied/synced from Debian, but to my knowledge all binary packages are rebuilt on Ubuntu?

Anyways, I did some digging [1] and found the build log for amd64 [2]. When searching for any of the troublesome dependencies, I see that they were installed from focal-proposed, for instance:

Get:105 http://ftpmaster.internal/ubuntu focal-proposed/universe amd64 golang-github-prometheus-client-golang-dev all 1.2.1-3 [100 kB]

So it looks like the newer versions were in -proposed, and prometheus built successfully the first time round. It then looks like the newer versions never migrated from -proposed to the -release pocket for unknown reasons and they are currently in groovy-proposed. Prometheus on the other hand, did end up in -release and without the dependencies it now fails to build.

(I am not sure how prometheus migrated to -release before its build dependencies were, I thought that was a requirement in order to avoid issues like this...)

I have run into same issue. The following build dependencies are not available on focal (the version constraints are higher than the available package versions in focal):

- golang-github-gophercloud-gophercloud-dev (>= 0.3.0~):

 Package: golang-github-prometheus-alertmanager-dev

- golang-github-prometheus-client-golang-dev (>= 1.2.1~):

 $ apt-cache show golang-github-prometheus-client-golang-dev
 Package: golang-github-prometheus-client-golang-dev
 Architecture: amd64
 Version: 0.9.2-0ubuntu3
 ...

I suggest to use opensource build tool BLDR, which always builds in clean environment based on the Build-dependencies in the control file and this errors could be avoided easily:

 bldr build ubuntu:focal
