Keys for apt-get need to be updated about acme-redirect HOT 2 CLOSED

Thank you for the tips.
Removed the entry with apt-key del
Then added your file with apt-key add kpcyrd.pgp
That made it work

Thanks.

The updated key is available here, depending on how you originally imported the key you need to update it differently, the strategy apt currently recommends is putting the file at /etc/apt/trusted.gpg.d/kpcyrd.gpg.

Unfortunately apt is somewhat buggy in that regard, if the expired key is in /etc/apt/trusted.gpg (which was deprecated by the latest debian release) you need to remove the expired key from there too or the key from /etc/apt/trusted.gpg.d/kpcyrd.gpg won't be picked up. On my systems it was fine just running rm /etc/apt/trusted.gpg /etc/apt/trusted.gpg~ but check with apt-key list first if there are still any keys in there that you need.
