I looked at the results of the autopkgtest of you package because it was 
showing up as a regression for the upload of gcc-12.

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure. Our arm64 workers are located in China, I 
wouldn't be surprised if the required connection isn't optimal, so I 
suspect increasing the timeout sufficiently is going to solve the issue, 
although making it more robust against connection issues would be smart 
too (e.g. retrying a small number of times in case of failure).

Also, as the autopkgtest spec says [1], please mark your test with the 
"needs-internet" restriction.

Paul
