This message is harmless in most cases, but can cause a switch to text mode while debconf is able to fallback to another frontend. It is also very worrying for users. As discussed on IRC, I have uploaded glibc 2.31-13+deb11u2 that fixes that issue by not trying to detect if debconf is available when the debconf frontend has already been loaded. You will find the corresponding debdiff attached. Regards, Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@aurel32.net http://www.aurel32.net
