Hi there,
An .deb installation on linux mint finishes with what looks like an uninterpreted html page as wizard (see : https://pastebin.com/iy9TsVhp).
.deb used is https://sourceforge.net/projects/dolibarr/files/Dolibarr%20installer%20for%20Debian-Ubuntu%20(DoliDeb)/10.0.4/
apt-get install -f was done.
apt update && apt upgrade too.
Rem
Recommanded installation from .tgz file worked. I recommand too ! 
Hi,
You always need to setup a complete LAMP before using the .deb
Your error was that php is not executed.
Really ?
It is said that the .deb package comes
packaged with Mysql, PHP and Apache or Lighttpd https://wiki.dolibarr.org/index.php/Dolibarr_for_Ubuntu_or_Debian
or
This distribution allows you to make an installation under Ubuntu with all prerequisites (Apache, Mysql, PHP) https://wiki.dolibarr.org/index.php/Installation_-_Upgrade
Yes it is comming with the right packages, but the configuration is missing.
So most of the time, the Vhost is not declared or PHP not enabled
Better to install first a working LAMP, then install dolibarr with .tgz package
Good to know.
I think I found why it didn’t work. conf.php was not executable.
cd dolibarr ; touch htdocs/conf/conf.php ; chown www-data htdocs/conf/conf.php
of the wiki should be followed by
sudo chmod 755 /var/www/html/dolibarr/htdocs/conf/conf.php
Hi,
Conf.php needs to be 644 during the installation then 444
755 is quiet dangerous
Thanks for advising, I am going to fix it.
