I've uploaded to unstable. There's what tracker lists as a regression in CI tests: https://ci.debian.net/data/autopkgtest/testing/ppc64el/s/squid/8297228/log.gz
I don't think that regression looks caused by krb5 after examining the log. Do you need me to request binnmu of libauthen-krb5-admin-perl and libpam-krb5-migrate-mit? I'm guessing not because it looks like that's already happening.
