Bug description:
[Impact]
* This issue affects users of the release-upgrade feature of
landscape.
* Landscape package monitor would previously race during an upgrade
and possibly grab apt locks, thus making the upgrade fail.
* The fix adds checks during package operations to make sure a
release upgrade is not in progresss.
[Test Case]
* in /etc/landscape/client.conf , set "apt_update_interval=1800" and
"log_level=debug" and restart the client.
* Launch a release upgrade from landscape-server. Look for messages
in the package-monitor logs stating "conditions not met"
[Regression Potential]
* Unlikely, as this has already been released to newer ubuntu releases
and is fairly well tested.
* Any issue with related changes would likely only affect the client
getting new package info, but won't affect other functionality.
[Original description]
Affected release: Ubuntu 14.04.5
Version of package: 14.12-0ubuntu5.14.04
Steps to reproduce:
1. Run do-release-upgrade to upgrade to 16.04.2.
2. Trigger the package-reporter to kick in while do-release-upgrade is
working but not having the package database locked.
3. Package database is locked by package-reporter, do-release-upgrade fails
to access it and exits.
Expected result:
Landscape detects that there's an release upgrade in progress and will wait
for it to finish.
Actual result:
PackageReporter locks the apt database, do-release-upgrade cannot access it,
exits with an error and may leave the system in an unusable state.
