I wanted to install elementary+ icons, but got an error while trying to add devs PPA:

E: The repository 'http://ppa.launchpad.net/cybre/elementaryplus/ubuntu bionic 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 tried various solutions I found but none of them worked. Can you please help?

This PPA has no releases for Juno (Bionic). You can force it by changing "Bionic" to "Xenial" in repo list file (/etc/apt/sources.list.d/) but I wouldn't recommend it.

Try these instead Uratu icons.
