Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye I'd like to install libc6:i386 to support an old proprietary printer driver. I've performed the following: dpkg --add-architecture i386 apt update When I attempt to install libc6:i386 via apt install libc6:i386 I am presented with a message indicating that most of the existing packages, including essential packages will be removed. Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages were automatically installed and are no longer required: [ seemingly all of the automatically installed packages on my system] Use 'apt autoremove' to remove them.

Need to get 3,579 kB of archives. After this operation, 13.7 GB disk space will be freed. You are about to do something potentially harmful. To continue type in the phrase 'Yes, do as I say!'

Done Building dependency tree... Done Reading state information... Done Calculating upgrade... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Directly after adding the new architecture and running apt update, an apt upgrade returns this: # apt upgrade Reading package lists... Done Building dependency tree... Done Reading state information... Done Calculating upgrade... Done The following packages have been kept back: gnupg gnupg-l10n 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded. which seems to indicate there's already an issue prior to attempting to install libc
