Did you follow the instructions and do you have debsuryorg-archive-keyring package installed?

Hello,

I try to run curl -sSL https://packages.sury.org/php/README.txt | sudo bash -x again, it complained about the signatures, however when I run apt update it worked ok.

Just to clarify, I installed this repository long time ago and it worked without issues until this weekend. I didn't change anything in my end.

Anyway, the important thing is it working fine though.

Thank you for your help.

Hello,

I had trouble installing debsuryorg-archive-keyring on debian bookworm (on only 1 of 5 servers)!, PUBLICKEY NOT FOUND was always the error. running "curl -sSL https://packages.sury.org/php/README.txt | sudo bash -x" from above alowed it to install and then update and upgrade worked.
