I'm not a Linux wizard so it took a few weeks to feel somewhat comfortable with Debian but now it is my prefered distro and I feel it was worth it. As I said, Debian 9 (Stretch) provides easy install of latest fpc and lazarus from Synaptic software manager. Plus newer versions of different applications.
A helpful tool is fsarchiver, that can make images of the installation so you can go back to earlier setups. In 5 minutes your back to normal if you break something.
FSArchiver is found on
http://www.system-rescue-cd.org/ and you make a live USB stick to boot from and clone/restore Debian.
Example backup:
fsarchiver savefs /media/mydisk/images/2016-07-16-debian.fsa /dev/sdb1
Example restore:
fsarchiver restfs /media/mydisk/images/2016-07-15-debian.fsa id=0,dest=/dev/sdb1
You should backup to a different disk than the rescue stick.
