I have php7.0 installed on Ubuntu 16.04 and I'm trying to install a forum software in apache2, but I get the following error:
In order to function correctly, the PHP XML/DOM extension needs to be available.
I tried to execute
sudo apt-get install php-xml
sudo apt-get install php7.0-xml
but these give me the following error:
php-xml: Depends: php7.1-xml but it is not going to be installed
When I try to install php7.1 from a PPA, I still get issues of dependencies from other PHP modules.
Any ideas how I can get php-xml installed without any dependency issues?
