Update issue with signature/public key

I have been using the OS for several years with no problem. Now when I try to install updates I get the following message.

" ppa.launchpad.net/gezakovacs/ppa/ubuntu focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D45DF2E8FC91AE7E"

Any help would be appreciated as I am not sure how to resolve. Thanks

Re: Update issue with signature/public key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D45DF2E8FC91AE7E

should do the trick.

Failing that if you delete and re add the PPA with

sudo add-apt-repository ppa:gezakovacs/ppa

you should pull in the new key.

But this is Debian not Ubuntu and the use of PPA's is not recommended.

Re: Update issue with signature/public key

Many thanks for the suggestions. You say PPA is not recommended. Has this problem arisen because I have loaded packages that are not supported by Q4OS? If so should I remove the packages that are causing this. Thanks Steve

Re: Update issue with signature/public key

So long as things continue to work, and if there is no other option, then having the PPA just introduces an extra something to be aware of. It only gets to be a bigger possible issue if you get conflicting libraries installed from the PPA that then clash with dependencies for Debian stuff.

As regards the key - this just happens.

Re: Update issue with signature/public key

With your advice I have removed the programs that seemed to be causing the problem with one exception "qtcore4-|10n" I looked at removing this but it looked like it is a dependency for many programs. Not sure if it is safe to remove this. Thanks Steve
