trying to overwrite shared '/etc/java-8-openjdk/security/java.security', which is different from other instances of package openjdk-8-jre-headless:i386 on Ubuntu 20.04

[Valentyna]

I`am unable to install openjdk-8-jre-headless:i386 on Ubuntu 20.04.
My OS:
lsb_release -rd
Description: Ubuntu 20.04.1 LTS
Release: 20.04

I get an error:
apt --fix-broken install

I think the reason is in difference of /etc/java-8-openjdk/security/java.security file in 32-bit and 64-bit package. String org.GNOME.Accessibility.,\ exists in 64-bit package, but doesn`t exist in 32-bit package.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug is rearing it's ugly head on more 20.04 installs with JDK 8 trying to upgrade to the latest

[Sam Volojiy (svolo)]

Tired of waiting for the distro owners to fix it, I forced the overwrite, which solved the issue and made apt is usable again:

`sudo dpkg --configure --force-overwrite -a`

Alternatively:

`sudo apt -o Dpkg::Options::="--force-overwrite" --fix-broken install`

This issue seem to be related 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. There are more details on this bug report - https://bugs.launchpad.net/ubuntu/+source/openjdk-8/+bug/1806265

I had a similar problem, but solved it by removing all JRE8 packages and leaving only JRE11.

The problem also exists on Ubuntu 22.04 sine version 8u342-b07-0ubuntu1~22.04.
In version 8u312-b07-0ubuntu1 everything works fine.
