Dear maintainer(s),

You recently added an autopkgtest to your package zalign, great. However, it 
fails. Currently this failure is blocking the migration to testing [1]. Can you 
please investigate the situation and fix it?

I copied some of the output at the bottom of this report.

Hello Team,

I took a look at this and it seems the upstream[1] is not active anymore and 
Ubuntu already has a long standing bug report[2] regarding the same issue which 
hasn't seen any progress yet.

I tried to add autopkgtests to zalign long ago, and if I remember correctly it 
was segfaulting
on some data on amd64 itself.

So can we skip the tests for the failing architectures ?

We should instead ask for _removal of this package_. Same version since 9 years 
and upstream
is dead too.
