 New PRs submitted to the project are run through regression tests, and one set
 of those is the 'autopkgtest' runs for several different architectures, called
-'Ubuntu CI'.  Part of that testing is to run all these tests.  Sometimes these
-tests are temporarily deny-listed from running in the 'autopkgtest' tests while

-'TEST-01-BASIC/deny-list-ubuntu-ci-arm64' to disable the TEST-01-BASIC test
-only on test runs for the 'arm64' architecture.
