ubuntu-support-status fails with exception if using libvirt from the ocata cloud-archive

[Michael Eischer]

Setps to reproduce:
1. Use Ubuntu 16.04.2 LTS
2. Add Cloud-Archive for Ocata: sudo add-apt-repository cloud-archive:ocata
3. Install libvirt-clients: sudo apt-get install libvirt-clients
4. Run ubuntu-support-status

Expected result:
List of support durations for the installed packages

Actual result:
Traceback (most recent call last):
  File "/usr/bin/ubuntu-support-status", line 135, in <module>
    pkg.name, support_tag)
  File "/usr/bin/ubuntu-support-status", line 45, in get_maintenance_status
    raise Exception("No Release file found for %s" % pkgname)
Exception: No Release file found for libvirt-clients

By Digging through the source code I've found out that the cloud-archive packages have a "Supported: 48m" field and are therefore considered by the release check but the package list is ignored as its origin and label are != "Ubuntu". Packages which have an equivalent in the standard ubuntu package sources silently fallback to the standard package. However, there is no equivalent for libvirt-clients and therefore ubuntu-support-status breaks.

Michael,

Thanks for reporting this. I'm seeing the same behavior. It looks like the ubuntu-support-status command from the update-manager package will need some updates to better handle cloud-archive packages.

Also marking this as high for cloud-archive even though it really isn't a cloud-archive issue. Appears to be an update-manager package issue.

It looks like that has been fixed sometime in the last two and a half years as I cannot reproduce this error:
