I added foreign architecture i386 to my Debian amd64 installation. How do I remove it? When I try this command: dpkg --remove-architecture i386, I am told to first remove all i386 packages.

Rejected edit from superuser.com/users/944626/benjamin-buch, but still a good comment: "You might need apt-get purge --allow-remove-essential ".*:i386" to remove libc and other essential packages. Be very careful with --allow-remove-essential because it will kill your system if you accidentally remove the 64 bit version instead of the 32 bit one!" Dec 23, 2022 at 5:08
I would use "purge" instead of "remove".
~# apt-get purge ".*:i386"
~# dpkg --remove-architecture i386
The "purge" keyword removes all configuration files associated with the packages you're uninstalling.

$ sudo apt remove `dpkg --get-selections |grep :i386 |awk '{print $1}'`
$ sudo dpkg --remove-architecture i386

1I would suggest that you change the grep to grep ':i386 '. this is because some other packages have i386 in the description text. @WGRM Jan 28 at 3:31
