Package: criu Version: 3.11-2 Severity: important Python2.7 will go out of upstream security support during the Bullseye development cycle. It is not safe to assume it will be included in the next release, so if you want to be sure criu can stay in Debian, please update it to the python3 version available from upstream..
Personally, I want to remove some packages I maintain, particularly python- ipaddr, which criu depends on during the Bullseye cycle, regardless of what happens to python2.7, so please update (python3 includes the ipaddress module, which was developed from ipaddr, in the standard library).
