Am I doing anything wrong?
no, this is likely due to this commit:
https://salsa.debian.org/debian/sbuild/-/commit/bd765329ea55f6f72ae53457c751c0698413c5e7
By default, this maps a query for "sid" to "unstable" which you do not have
defined. You could try renaming your "sid" schroot to "unstable" and if it
works, then that is indeed the bug.
I'll have to think about how to best fix this...
Thanks for the quick reply!
Yes, it seems related to the handling of aliases.
In case this happens to somebody else, there is a simple
workaround: I added "aliases=unstable" to the schroot snippet
and then it worked again.
Thanks.
