Thanks for the response. My mind somehow converted 2.33 into 2.3.3 so I thought 2.3.3 < 2.4, thanks for helping me identify that mistake.
I see now that this is the real problem: $ sudo apt install libc6-i386 The following packages have unmet dependencies: libc6-i386 : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.3 is to be installed E: Unable to correct problems, you have held broken packages. And I can see that version 2.31-0ubuntu9.2 is available for me to install: $ sudo apt list -a libc6 libc6/now 2.31-0ubuntu9.3 amd64 [installed,local] libc6/focal-updates 2.31-0ubuntu9.2 amd64 libc6/focal 2.31-0ubuntu9 amd64 libc6/now 2.31-0ubuntu9.3 i386 [installed,local] libc6/focal-updates 2.31-0ubuntu9.2 i386 libc6/focal 2.31-0ubuntu9 i386 So I guess the solution is to install this previous version of libc6: $ sudo apt install libc6=2.31-0ubuntu9.2 Will this cause my system to become unstable? I don't feel quite safe running this command blindly.
