Can anyone tell me what I need to do to fix this? |

Save your config to your home folder
| Code: |
sudo dpkg --force-all --configure -a
sudo dpkg --purge --force-depends apache2
sudo apt --fix-broken install
sudo apt-get -f install
sudo apt update
sudo apt upgrade
sudo apt install apache2

Thank you. OK running through those steps it warns me that
'/var/www/html' and '/etc/apache2/sites-available'
are not empty so not removed when I do the purge
But the install still generates the dependency error |

Debian wants to install apache2-data = 2.4.66-1~deb12u1 while your sury has apache2-data = 2.4.66-1+0~20251205.20+debian12~1.gbp6076c7
| Code: | sudo apt --fix-broken install
sudo apt-get install apache2=2.4.66-1+0~20251205.20+debian12~1.gbp6076c7 |
this will install the sury version.
OR
you remove sury from your source list and install the debian apache- |

ok so removing the sury references in the source.list (both php.list and apache.list and running
| Code: | sudo apt --fix-broken install
sudo apt-get install apache2 |
I get
| Code: | | apache2 : Depends: apache2-data (= 2.4.66-1~deb12u1) but 2.4.66-1+0~20251205.20+debian12~1.gbp6076c7 is to be installed |
Running
| Code: | | sudo apt-get install apache2=2.4.66-1+0~20251205.20+debian12~1.gbp6076c7 |
(without the Sury list in place)
I get
| Code: | Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package apache2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libapache2-mpm-itk:armhf libapache2-mpm-itk
E: Version '2.4.66-1+0~20251205.20+debian12~1.gbp6076c7' for 'apache2' was not found |
It's like something strange has happened to the main apache2 package |

Thank you for this We are making progress!!
I have now successfully removed apache and reinstalled it. So I can see a running webserver that is rendering PHP code as text.
I understand that to fix this I need to install and enable the relevant PHP module. But I note that /usr/lib/apache2/modules is missing mod_php7.4.so (which is the version of PHP I need if I do php -v). I think the installation package that contains that is
libapache2-mod-php7.4
I can see php7.4.conf and .load in /etc/apache2/mods-available
| Code: | Package libapache2-mod-php7.4 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libapache2-mod-php7.4' has no installation candidate |
Any ideas for next steps?
Thnk you |
