Comment 1 for bug 1882347

oem-stella.cmit-abra-meta_20.04ubuntu1.dsc in the referred PPA is prepared as if for the OEM archive.
For Ubuntu Archive the packaging should point at the -ubuntu branch, not the -oem branch.
And version number should be 20.04~ubuntuX, not 20.04ubuntuX.

I think you are asking for somebody from the OEM team to sponsor oem-stella.cmit-abra-meta_20.04ubuntu1.dsc into the focal stella.cmit suite.

However note, it seems like cmit.abra-focal-oem branch is missing from the git repository, please push it.

Looking at the git repository cmit.abra-focal-ubuntu branch, it looks correctly prepared for the Ubuntu Archive upload.

However, http://hp.archive.canonical.com/dists/focal/stella is referenced in the apt source list, but is not available.

Setting bug report to incomplete:

1) please ensure the referenced suites the sources.list snippet match reality and are published. (i.e. either create focal/stella, or drop it from the sources snippet, as needed)

2) please push the -oem packaging branch to the repo

3) please upload/publish the oem version of the metapackage (20.04ubuntu1) in the oem archive
