The instructions to add the OBS signing key break the ability to add PPA's on Mint 19.x and Mint 20.

Hi,

https://software.opensuse.org/download/package?package=ungoogled-chromium&project=home:ungoogled_chromium

This line sudo wget -nv https://download.opensuse.org/repositories/home:ungoogled_chromium/Ubuntu_Focal/Release.key -O "/etc/apt/trusted.gpg.d/home:ungoogled_chromium.asc" does not correctly add the key and on subsequently trying to add PPA to the sources the partially installed ungoogled_chromium key causes failure to import the PPA signing key.

E: The repository 'http://ppa.launchpad.net/phoerious/keepassxc/ubuntu focal InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

The solution - on adding the ungoogled-chromium repo the key can be correctly added with this alternative command

Focal / Mint 20 wget -nv https://download.opensuse.org/repositories/home:ungoogled_chromium/Ubuntu_Focal/Release.key -O /tmp/home:ungoogled_chromium.asc; sudo apt-key add /tmp/home:ungoogled_chromium.asc

Bionic / Mint 19.x wget -nv https://download.opensuse.org/repositories/home:ungoogled_chromium/Ubuntu_Bionic/Release.key -O /tmp/home:ungoogled_chromium.asc; sudo apt-key add /tmp/home:ungoogled_chromium.asc

Please consider updating the instructions at https://software.opensuse.org/download/package?package=ungoogled-chromium&project=home:ungoogled_chromium

Cheers

Hi, on checking this issue on a default Ubuntu install it appears the issue caused by the current instructions is Mint specific.

I'm using Linux Mint 19.3 and I can confirm the issue. smurphos' fix works.
