I attempted to update via the Software Update. Received error message of 'package operation failed'. So I attempted to run it in the terminal. Below is what I received in response. I have attempted other fixes that I found in this forum (including changing the server from the United States to the main server, running autoclean and autoremove commands, and restarting my computer). I tried the suggestion from this post libpcre2-dev : Depends: libpcre2-posix3 (= 10.39-3+ubuntu18.04.1+deb.sury.org+1) but it is not installed but it did not work.

I am still fairly new to Ubuntu/Linux, so excuse my ignorance. Thank you.

You might want to run 'apt --fix-broken install' to correct these.

Should you have the third party deadsnakes ppa repository installed, it is likely causing this conflict.

Remove the deadsnakes ppa repository, run add-apt-repository command with the -r (remove) flag:

sudo add-apt-repository -r ppa:deadsnakes/ppa

Allow apt to make the required fixes

sudo apt --fix-broken install

Re-run apt upgrade, e.g.

sudo apt update -y && sudo apt upgrade

I was able to solve the issue.

The issue was I had the 'deadsnakes' repository installed. So I disabled it and re-ran the command 'sudo apt --fix-broken install'.

This fixed the issue and I was able to update using the Software Updater.

Thank you all for your help!
