<p>Hello, I am using Linux Mint 20.2 Uma 64-bit with Mate desktop on
my computer. Today I updated the machine in terminal as superuser
by passing the following command <b>apt-get update &&
apt-get upgrade </b>. <br>
</p>
<p>1. I received the following invalid signature key message output
as follows:<br>

therefore disabled by default.<br>

<p>2. I am using the openSUSE build service to aquire a prebuilt
binary package of sane-airscan and have the following sources
entry added in Update Manager -> Software Sources -> deb
<a href="http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/" target="_blank">http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/</a>
/</p>
<p>3. I typically update the desktop here every few days and have
had no signature issues for quite some time.</p>
<p>4. I did attempt the following by using GUI: Update Manager ->
Software Sources -> Maintenance -> Add missing keys <br>
</p>
<p>5. I then attempted to once again update APT cache within update
manager (not bash terminal this time) with the following error
output: <b>Failed to download repository information </b>the
following dialog is shown below this message -> W:GPG error:
<a href="http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04" target="_blank">http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04</a>

<p>I am wondering of what is the best step to proceed with this
matter? I understand that I could possibly disable the repository
quite easily in update manager. Then I would no longer receive
updates for sane-airscan though. I thank you for help with this if
able.</p>
