Describe your issue

I am trying to install MediaWiki on YunoHost, but the installation fails. I have a fresh YunoHost install on a virtual machine on a local server. It is running a fresh install of Debian 12.13.0 with a minimal install; I selected the basic utilities and SSH server only when I installed the OS.

It appears that there are problems with getting some packages. The warnings from the logs that seem relevant are shown below. What are some things I could try next?

Welcome @dubiousDonkey
What is your cpu architecture ?

arch

It is x86_64.

Could you share the output of

cat /etc/apt/sources.list.d/extra_php_version.list
sudo yunohost tools regen-conf apt --dry-run --with-diff
apt-cache policy php8.3

This is the output:

deb [signed-by=/etc/apt/trusted.gpg.d/extra_php_version.gpg] https://packages.sury.org/php/ bookworm main
[sudo] password for *redacted*:

I rebooted the server before I shared that output because I could not reach the webadmin. I gave the install another try and it was successful this time. Go figure.

recent discussion about fact that sury.org is handled by a unique person.

( FR (sorry didn’t read) Le dépot http://sury.org qui fourni les dernières versions de php est maintenu par une seule personne et il arrive parfois des soucis de certificats ou d’accès .

une discussion récente en anglais à ce sujet. )
