Release update from 22.04 to 24.04 fails

[orbanp]

Hello Everyone,

Trying to upgrade from 22.04 to 24.04 and it fails at the second step, at "setting new SW channels".
The error message I am getting is as follows:

W:Updating from such a repository can't be done securely, and is therefore disabled by default., W:See apt-secure(8) manpage for repository creation and user configuration details., W:GPG error: https://dl.winehq.org/wine-builds/ubuntu jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F, E:The repository 'https://dl.winehq.org/wine-builds/ubuntu jammy InRelease' is not signed.

I do have PlayOnLinux (POL) version 4.3.4 installed, and a number of Windows program installations using it.
I would like to keep POL and the programs running under it with their setups.

My present system is as follows:

Operating System: Kubuntu 22.04
KDE Plasma Version: 5.24.7
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel Version: 5.15.0-125-generic (64-bit)
Graphics Platform: X11
Processors: 6 × Intel® Core™ i5-8500 CPU @ 3.00GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 630

Thanks for any help, Peter

You will want to update after fixing this, as it breaks regular updates as well
