Comment 32 for bug 1768379

The following tests have a history of failures and shouldn't be considered regressions:

dulwich [bionic/s390x]
snapcraft [bionic/all arches]
python-mechanicalsoup [bionic/all arches] These LinkNotFoundErrors also occurred in cosmic and when the bionic/s390x version was triggered by pytest-mock/1.7.1-1 so its not related to my SRU.
netplan.io [bionic/all arches] test_eth_dhcp6_off seems flaky to me as its failed with other triggers
