Update Manager [SOLVED]

[gdj]

I installed Mint and it seems to be working correctly. I then managed to install Wine to run a couple of windows programs. I installed my windows programs using Wine and they appear to be working correctly.

However when I use the update manger I get the message

GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672FThe repository 'https://dl.winehq.org/wine-builds/ubuntu bionic InRelease' is not signed.

If I close the message and refresh Update manager it then gives the message my system is up to date. Next time start up my laptop I again get the above message.

I have not been able to find a solution to this problem and would be grateful for any suggestion as to what I should do.

Thanks GDJ

That means you added the WineHQ repository, but not the public key for it. It also means you are unlikely to have installed Wine from that repository and instead installed the version that Linux Mint ships with.

You can check your currently active Wine version by running:

Code: Select all

wine --version

If the version is 3.x instead of 4.x then I suggest you simply remove the WineHQ repository again. You can do so in the Software Sources tool, accessible from the main Mint menu or Update Manager's Edit menu. Just find the WineHQ entry on the Additional Repositories tab, select it and click the button to remove it.

Thank very much gm10 for your explanation. I found I have version 3 running. So I followed your suggestion it appears to have sorted the issue.
