I am suddenly getting this error while trying to update my Ubuntu 20.04 system.
The following packages have unmet dependencies: openjdk-8-jre:i386 : Depends: openjdk-8-jre-headless:i386 (= 8u272-b10-0ubuntu1~20.04) but 8u265-b01-0ubuntu2~20.04 is installed openjdk-8-jre-headless : Breaks: openjdk-8-jre-headless:i386 (!= 8u272-b10-0ubuntu1~20.04) but 8u265-b01-0ubuntu2~20.04 is installed openjdk-8-jre-headless:i386 : Breaks: openjdk-8-jre-headless (!= 8u265-b01-0ubuntu2~20.04) but 8u272-b10-0ubuntu1~20.04 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).Trying 'apt --fix-broken install' gives this output:

E: Sub-process /usr/bin/dpkg returned an error code (1)I'm not sure what this means or what to do to clear this error. Any advice? Thanks.

This issue seem to stem from the conflict between the OpenJDK and Oracle's own DEB distributions for Focal, especially if you've used the webupd8 PPA in the past to install it. I solved it by forcing the override:
sudo apt -o Dpkg::Options::="--force-overwrite" --fix-broken install
You can also force it directly with dpkg by running
sudo dpkg --configure --force-overwrite -a
