It could be observed in Cosmic with systemd security updates failing to install partly due to 239-7ubuntu10.10 being smaller than 239-7ubuntu10.8 when comparing them as strings: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-disco/disco/amd64/u/unattended-upgrades/20190318_182031_fe4fe@/log.gz [Test Case] * The fix includes the extension of the build-time test cases to cover package sets with which u-u fails with without the fallback: ... Running ./test_rewind.py with python3 DEBUG:root:APT::VersionedKernelPackages is not set DEBUG:root:adjusting candidate version: test-package=2.0 ... With the unfixed version the test case fails here because u-u tries to upgrade test-package to version 12.0 because it does not find version 2.0 smaller. [Regression Potential] * The change is very small and isolated, but fixing it revealed the issue fixed in LP: #1821101. Since the found issue's fix introduces fallbacks when apt's resolver can't find a the solution it is unlikely that other failures are triggered by the fix.
