Lazarus not installing on Ubuntu

[gga96]

I am moving from Window to Ubuntu and have been trying to install Lazarus.

The default installation on Lazarus is 1.0.10 but I have been using 1.4.4 and FPC 2.6.4 on Windows.
For the last 3 days I have been following online advise and failed on all attempts to install Lazarus 1.4.4 + 2.6.4 on Ubuntu 14.04 64 bit.
 
I downloaded the following files from your web site:

Being new to Ubuntu I do not know how to correct the error!
I have just read "Installing .deb packages on Ubuntu" but I do not think it applies.

Could you please help to get Lazarus up and running?

Regards
Glen

Uninstall everything you install from ubuntu repository. They have splitted runtime packages while the one from here is a single all-in-one package.

[JD]

Like Leledumbo said, uninstall everything you installed from the Ubuntu repositories. Then

a) copy all the deb files you downloaded from the Lazarus website into a temporary directory
b) open the directory in a terminal & then
c) type & run the command sudo dpkg -i *.deb at the terminal prompt

It will install the packages you downloaded. That's all you need to do.

JD

[gga96]

Thank you both.

I have used Ubuntu Software Center to remove FPC and Lazarus.

I don't know what else I can do to purge the system of previous attempts

I tied again to install this time using sudo dpkg -i *.deb the terminal output follows:

[Leledumbo]

Don't uninstall from Ubuntu Software Center as it may only uninstall top level package (or with some other dependant packages but surely it's not clean enough since at least fp-units-gfx is still installed). Use dpkg -l from terminal to see which fp-units-* are still installed and uninstall them using dpkg -P.

[gga96]

Thanks Leledumbo I have used your advice and am now at:

I then tried to purge:

I never seem to clear the decks to achieve a clean install.
I am a novice with Linux not a systems engineer so I cannot debug the errors.
I appear to be going round in circles because the install always fails at the first package:

dpkg: dependency problems prevent removal of fp-units-rtl-2.6.4:
 fp-compiler-2.6.4 depends on fp-units-rtl-2.6.4 (= 2.6.4+cqr-1~trusty).

You still have fp-compiler installed (and probably some other fp, too). I don't use Ubuntu so please figure these out yourself (it's only fpc and fpc-src on Arch based systems). Don't attempt to do dpkg -i if the purging fails, make that succeed first.

[gga96]

Thanks for your help Leledumbo sorry you cannot work with Ubuntu.

Does a Ubuntu person know how to remove the fp compiler that will not purge (see previous posts)?

glen@backend1:~$ dpkg -l fp-units-*

I cannot install deb files until fp-units-rtl-2 is purged.

Some progress has been made, I managed to purge the system and have attempted the install.

The install went like this :

I am not aware of any serious errors this time.

I then run Lazarus by using the menu Applications>Development>Lazarus the Configure Lazarus IDE dialog appeared.

The Lazarus tab warned it could not find directory /use/lib/lazarus/1.4.4 I looked around and found /usr/share/lazarus/1.4.4, when I entered that into the dialog it responded "Warning: directory ideintf not found".

I stopped at this point to avoid corruption.

What do I do to fix the problem?

I'm also using Lazarus 1.6 RC2 with FPC 3.0 on Ubuntu 14.04 64 bit. The installation is pretty simple. Here's my steps:

1. Download all the .deb files for your platform from here: http://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%201.6RC2/

2. Once you got all the .deb files, install them in this order:

Code: Bash  [Select][+][-]

1. $ sudo dpkg -i fpc-src_…_amd64.deb
2. $ sudo dpkg -i fpc_…_amd64.deb
3. $ sudo dpkg -i lazarus_…_amd64.deb

replace the … with the correct version string.

3. Run this command to satisfy the dependencies:

Code: Bash  [Select][+][-]

1. $ sudo apt-get -f install

After the installation finishes, open the unity and search for Lazarus. Click to run it.

Good luck!

Thanks to ttomas and bee.

I used synaptic to remove Lazarus 1.4.4
Downloaded Lazarus 1.6rc2 and installed as bee instructed.
The install looks OK to me,  here is the output:

I did not understand "open the unity and search for Lazarus. Click to run it" I used the Applications menu on my 14.04 system.

When I started Lazarus the same things happened.
It expects to find data in /usr/lib/lazarus and when I enter /usr/share/lazarus/1.6RC2 it gives the warning "directory ideintf not found"

The names are different but the errors are the same!

Cheers
Glen

[Leledumbo]

Search where lazarus is actually installed (see from `dpkg-query -L lazarus` output), that's where it should point to. The IDE has heuristic but this can of course fail because every distro may put it in different directories depending on the package management policy.

[bee]

I did not understand "open the unity and search for Lazarus. Click to run it" I used the Applications menu on my 14.04 system.

I thought Unity is the default Ubuntu desktop shell today. How could you don't know about it? Using the old Applications menu isn't even available by default, you have to install it from a third party repo.

When I started Lazarus the same things happened.
It expects to find data in /usr/lib/lazarus and when I enter /usr/share/lazarus/1.6RC2 it gives the warning "directory ideintf not found"

I think your system has been cluttered by many junk files and configs from previous failed installations. I installed FPC/Lazarus on a fresh Ubuntu 14.04 system, and my steps worked so smooth without any errors.

[gga96]

Thanks Leledumbo the output is 904 kB, the common root director is  /usr/share/lazarus/1.6RC2/  the 'ideintf' only appears as a subdirectory 'components/ideintf/'.
Any other sugession?

Regards
Glen

P.S.
bee I installed MythTV in 2013 it installed clean out of the box and the system has runs non stop since. It is only now after 20+ years of Delphi that I am looking at Linux as an alternative to Windows.
