I couldn't able to install new applications or run some of the existing apps or get software updates because of this issue.

Problems:

First of all, you have some Ubuntu Impish repositories that I assume were manually added. Ubuntu Impish (21.10) is now EOL so it's no longer supported and the repositories have since been disabled.

Next, the AMCG ppa was last available for Ubuntu Xenial.

Under "Overview of published packages", click on the dropdown menu for "Published in: Any series" filter and you will see this PPA was only available for Xenial and Trusty.

Additionally, Anbox support ppa is no longer necessary on kernels newer than version 5.0. Any Ubuntu version newer than 19.04 does not need the extra kernel modules provided by the anbox-support PPA.

Solution:

The easiest solution would be to delete or comment out the lines for Ubuntu Impish in your sources list file.

Then, delete the unneeded PPA repositories by using the add-apt-repository -r command:

sudo add-apt-repository -r ppa:amcg/ppa
sudo add-apt-repository -r ppa:morphis/anbox-support

Also, it looks like you may need to reinstall the Brave browser because it's throwing a signature error. Be sure to backup your current Brave Browser in case you lose your bookmarks and settings. Although this is probably outside of the scope for this question, you can ask the community and open a new question if you need help with this.

And then run:

sudo apt update

and if you get no errors:

sudo apt full-upgrade

and if you have problems you may need to run:

sudo apt -f install

with no packages mentioned — just run the last command as is and it will try to fix any problems with broken packages. Always be sure to pay attention to the output and only select Y if you are sure you want to proceed as this may delete or uninstall packages.

When you no longer have any errors, verify everything is updated/upgraded:

sudo apt update
sudo apt full-upgrade
