ok let’s try following

OK - that’s got lighthttpd running again and I can hit the placeholder page. Great - thanks!
So, I think we’re at the point you wanted to get to (which was to get the base distro upgraded to Buster) and then, if I recall, it was PHP next because if I try the /nextcloud page I get the internal server error message which started off this whole conversation.
let’s check what version is installed

Hi -
OK - done that. Web service now running again, and I am able to hit the root placeholder page.
When trying the /nextcloud URL I now have something new. Instead of the generic “Internal server error” message I had been seeing previously, the system is now displaying a Nextcloud look-and-feel web page (logo, etc…) but with the following displayed in the middle of the page which I think was what you were originally working towards in respect of getting a response and then helping me to fix PHP -
Error
PHP module cURL not installed.
Please ask your server administrator to install the module.
PHP modules have been installed, but they are still listed as missing?
Please ask your server administrator to restart the web server.
let’s see if we can install the required module
apt update
apt install php7.3-curl
dietpi-services restart
Thanks (again)
It was looking encouraging and then this popped up when I attempted to install the following came up -
apt install php7.3-curl

Thought I’d use some initiative and try
apt install php7.3-common
, but it reports that this module is already at the newest version (7.3.31-1+0~20210923.88+debian9~1.gbpac4058).
The key seems to be in these held broken packages.
Ah it’s still the incorrect package from stretch. Let’s check what is installed

let me ping our developer MichaIng to get this sorted and cleaned up. Still some old packages.
Many thanks - I’ll keep an eye open for the next update 
So the issue is that PHP module packages depend on an exact version of php-common and hence when Ondrej’s repository is removed, no new module can be installed. php-common also cannot be downgraded as long as any module from Ondrej’s repo is installed.
Yeah looks like all of them need to be downgraded to the Debian Buster packages then.
First of all purge the remaining PHP8.0 packages:
G_AGP '*php8.0*'
There are also config files from phpMyAdmin left. If you don’t use it, purge it as well:
G_AGP phpmyadmin
If you want to use it, I suggest to install it via dietpi-software after the PHP module reinstalls below, which will pull the latest upstream version of phpMyAdmin, instead of the Debian package.
Then try to reinstall + downgrade all PHP (7.3) packages this way:
apt install --reinstall --allow-downgrades $(dpkg --get-selections '*php*' | mawk '{print $1}')
MichaIng
Thank you for joining this conversation. Joulinar has been absolutely brilliant up until this point, but needed your input - so I thank you again.
The first two commands worked fine from what I could see, but when I tried the last command this is what I saw -
apt install --reinstall --allow-downgrades $(dpkg --get-selections '*php*' | mawk '{print $1}')
