Error installing Wine on Ubuntu

I'm using Ubuntu 20.04 and tried everything to install Wine on it but all that I get is this error

E: The repository 'http://ppa.launchpad.net/wine/wine-builds/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I'd appreciate if anyone could help me, I need to use Photoshop CS6 on Linux.

Solution 1:

Your output suggest that you are doing it the hard way. Here is an easier way:

1. Delete that PPA.

2. Since you just changed your apt sources, run sudo apt update

3. Install the 20.04-compatible Wine from the Ubuntu Repositories: sudo apt install wine

Do not skip any steps. Stop if you encounter errors.
