Since there is no Bug channel, I will post it where relevant.

Please note that the Debian installation process  for Latest Lazarus
v1.8.0 is broken for some reason using gdebi
Reason. Although fpc 3.0.4 is installed and verified, the debian
version of Lazarus installer/gdebi cannot find it.
gdebi returns the following:
ERROR:
Dependency is not satisfiable:
fpc (=3.0.4)|fp-compiler (=3.0.4)

This might throw off prosepective users

Installing from source works perfectly and Lazarus finds the fpc
compiler.

Did you post a bug in the bugtracker)

What is the package name of the installed FPC?   Debian will only
install based on installed packages, and will ignore handinstalled
versions

e.g. are fpc- and fp- in

dpkg-query -l 'fp*'

?

As I explained before, add backports to sources.list and Debian
Stretch will happily install both Lazarus 1.8 and FPC 3.0.4 from its
own repositories using apt.
Instructions https://backports.debian.org/

@dryzone

Many users have problem installing Lazarus on Linux. Each distro may
show different error and even on the same distro but different
versions the error can be different. "Dependency is not satisfiable"
usually happens when installing latest version of Lazarus on old
version of Linux. What distro and version are you using?

I tested installing Lazarus 1.8.0 on Ubuntu 16.04, the Gdebi managed
to automatically install the missing packages:

Installing Lazarus 1.8.0 on (current latest) Ubuntu 17.10 is easier
although it still showing annoying errors but it worked:

Handoko, only Ubuntu - and only some versions - have problems for some
people.
The packages in Debian Stretch back-ports are the recommended way to
install Laz 1.8 and FPC 3.0.4 outside of Freepascal's own
distributions.
These are maintained by Debian maintainers and simply work without any
problems.

Although I appreciate your efforts do not confuse people.
The best and supported ways to install are either the packages from
official freepascal website OR the official Debian packages. The
latter work on all platforms based on Debian Stretch + backports or
Debian testing+

See also my answer here http://forum.lazarus.freepascal.org/index.php/

The official Debian deb's are supported - on the package level - by
official Debian maintainers and duely tested, probably better than
freepascal's own distributions. Debian is very rigid.
The official fpc/lazarus deb's are supported by FPC and Lazarus own
maintainers.

I've never tried that trick. But if it works, please write a wiki page
so I can direct new users to the page or better an installation guide
on the download page.

It is not a trick. It is an official way to install.
