onit's questions

I have been following wine's steps to install winehq, but despite I've seem to be done all I can, I keep getting this error:

The repository 'http://ppa.launchpad.net/wine/wine-builds/ubuntu eoan Release' does not have a Release file.
E: The repository 'http://ppa.launchpad.net/wine/wine-builds/ubuntu eoan Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

If anybody could shed a light as to where I should go from here, I'd appreciate it. Thanks.

Here is the updated output, after I've tried the suggestions below:

antonio@mclinux:~$ sudo dpkg --add-architecture i386 
antonio@mclinux:~$ wget -nc -qO- https://dl.winehq.org/wine-builds/winehq.key | sudo apt-key add -

Could you help me see what's going on?

Cheers,

I've upgraded from 19.04 to 19.10 and after adding the following, I've gotten myself in a login loop, where I can enter the password and the screen goes blank:

$ gedit ~/.profile

Added the following to the bottom: xrandr --newmode "1024x768_60.00" 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync xrandr --addmode VGA1 1024x768_60.00

It immediately recognized the resolution and was working fine, until I rebooted it.

When I'm on root's home folder and ls, I dont see the user listed.

Any help is greatly appreciated! Thanks!
