Installation on CentOS 8 stopping

[userdarc]

We have a problem installing Pi-hole on a CentOS 8. The installer script stops on this position:

[✓] Check for existing repository in /etc/.pihole
[✓] Update repo in /etc/.pihole

[✓] Check for existing repository in /var/www/html/admin
[✓] Update repo in /var/www/html/admin

[i] Main Dependency checks...
[✓] Checking for php-pdo

Unfortunately we can find no installer log to debug the process.

Does anyone have a clue how the get some information about whats going wrong here?

Thank you very much!

CentOS 8 is not a supported OS. There are some dependencies that are not available.

Hi jfb,

we know that is is actually not supported, is there any workaround or something?

[jfb]

Here are some notes from a developer on this topic - this has not been tested, so your results may not be satisfactory.

Looks like lighttpd & lighttpd-fastcgi are not available in the CentOS 8 EPEL repo.

I would suspect if a user was to install lighttpd and lighttpd-fastcgi manually. If not installed via yum/dnf, they would also want to remove them from the dependency list before re-running the installer.

As noted above, the lighttpd packages that we require from the EPEL repositories do not appear to be available. CentOS 8 will remain unsupported until the packages are available and/or we remove the lighttpd from the project.

That said, I have provided a workaround below that will compile lighttpd from source and edit the install script to remove lighttpd from the dependencies. I hope this helps
