For others who may have the same issue, here’s what I did to temporarily workaround:
$ sudo dpkg-deb -R percona-server-mongodb-server_4.4.8-9.buster_amd64.deb tmp
$ sudo vi tmp/DEBIAN/conffiles
Remove the two lines below in tmp/DEBIAN/conffiles, leaving the ones with the absolute pathnames:
$ sudo dpkg-deb -b tmp percona-server-mongodb-server_4.4.8-9.buster_fixed_amd64.deb
$ sudo dpkg -i percona-server-mongodb-server_4.4.8-9.buster_fixed_amd64.deb
Percona team, appreciate if this could be fixed, and support for Debian bookworm added in your distribution. Apart from this hiccup, I love what you guys are doing to make enterprise features available in the community distribution, it’s definitely in the right spirit of the community.
