As a standard user, this is not the behavior that I would expect from
the package manager.  I can usually safely mix packages from stable,
testing and more thanks to a proper apt pinning configuration, and the
package manager tells me if I can upgrade a package e.g. from testing
without wrecking havoc my system.  But I understand your point of view
and the solution chosen.

Thank you for your feedback!

Hi Damien,

Yes, these two versions are not fully compatible.  I didn't put in a
version restriction because mixing packages from testing into a stable
installation can result in breakage (such as you've ran into).  If you
really want to do so, make sure that you pull not only the package
from testing, but all the things that reverse-depend on it.  For
certbot, the easiest way to do that is to specify that you want to
install the leaf package from testing (python3-certbot-apache), rather
than the middle package (certbot, or python3-certbot).  That should
reliably upgrade certbot itself, if it's necessary to do so.

That said, I'll talk with upstream and see if I can add some level of
version protection to keep it from happening in the future.

Thanks for your report!

You can notice that module python3-certbot-apache is also installed, but
with a lower version number.

I could fix the issue by upgrading python3-certbot-apache to version
1.1.0-1.


Thank you for your work on packaging this tool!
