I have some 'unmet dependencies'. I can't remove them, I can't upgrade them. I have googled and tried quite a few tricks(including: 'sudo apt-get --with-new-pkgs upgrade', 'sudo apt install packages-names', 'sudo apt-get dist-upgrade', sudo aptitude then '+' then 'g g'.., sudo apt install -f and some more) but still no luck! Need some help. Thanks in advance.

    Calculating upgrade... Done

  libdrm2 libdrm2:i386
0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded.

Please have a look at the screenshot of my terminal. I am using Ubuntu 20.04.

I have got that problem solved, by removing all 32bit apps along with the architecture and then I dist-upgrade:

sudo aptitude purge `dpkg --get-selections | grep ":i386" | awk '{print $1}'
sudo dpkg --remove-architecture i386
sudo dpkg --print-foreign-architectures
sudo apt update && sudo apt upgrade && sudo apt dist-upgrade

sudo apt-get purge ".*:i386"
sudo apt update && sudo apt upgrade && sudo apt dist-upgrade

Though now a new error is showing at update:

E: Could not get lock /var/lib/apt/lists/lock. It is held by process 1683 (packagekitd)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/

So I have to run sudo service packagekit restart every-time of update I don't know why!
