Having issue with apt-get update
Hey, I’ve seen this happen before. It usually means there’s an issue with the repository’s signing key or the repo configuration.
A quick way to fix it is to make sure you’ve added the GPG key for that PHP repo and that your /etc/apt/sources.list.d/ entry is correct. You can try running:
wget -qO - https://packages.sury.org/php/apt.gpg | sudo gpg --dearmor -o /usr/share/keyrings/php-archive-keyring.gpg
And then update the source list to reference the keyring:
deb [signed-by=/usr/share/keyrings/php-archive-keyring.gpg] https://packages.sury.org/php/ bookworm main
After that, run sudo apt-get update again — it should fix the warning.

It looks like the SSL certificate for packages.sury.org has expired, which is why apt-get update is showing the 503 error.
This issue is on the repository’s side, not on your server.
You can try these steps:
Run:
sudo apt-get clean
sudo apt-get update --allow-unauthenticated
(only temporarily — not for production use)
If the error still appears, wait a few hours. The maintainer (Ondřej Surý) usually renews the certificate quickly.
Alternatively, you can disable the PHP repository temporarily by commenting out the line in
/etc/apt/sources.list.d/php.list,
and run sudo apt-get update again.
Once the SSL certificate is renewed, re-enable the repo and update normally.
Hope this helps!
