I had lazarus 2.2 installed on Linux Mint. As I couldn't remove it, I followed charGPT's suggestion and used the Linux Locate command and removed all files that had "lazarus? (without the quotes) in the name. Then I downloaded the latest 64-bit version from the lazarus download site and tried to install it with dpkg. I received several errors and the installation is not working. I will put below a copy of the Linux Mint console screen with the errors.

I'm looking to replace freepascal because IDE 2.2 no longer opened projects created by itself.

You need to install fpc packages with dpkg, downloaded from lazarus repository.

=========================================================

I'm starting to believe that I will never have Lazarus on my Linux Mint again.
For many years I tried to use Linux without success with installations of all types. So I started thinking that to use Linux a person needed to be an expert or have one nearby.
Linux Mint gave me new hope.
But all the problems started again. I wonder why the Lazarus installation doesn't work. Or I can't make it work.
Can anyone tell me what I should or can do to install the

lazarus-project_3.4.0-0_amd64.deb

on my Linux Mint?

Or can I only successfully install it on Windows?

I appreciate any help.

<snip>

I'm using Lazarus under different Linux distros since 25 years, and I never found a platform where it doesn't install and work properly, so I've collected a fairly good experience.

You have three ways to install Lazarus:

1) if the distro provides a Lazarus package, you may try to take advantage of it. That means in a Debian distro using apt-get or in a Red-Hat style distro using yum or dnf. Usually either it doesn't work at all, or it's an old obsolete version. If it doesn't work perfectly at the first attempt, forget about what your distro provides.

2) get rid of anything related with Lazarus and fpc your distro has provided, and when positively you get a "not found" both for "startlazarus" and "fpc" invocation, download and install the three packages suggested by Mattias Gartner *from the fpc-lazarus website*, selecting your architecture and your package format (deb in your case) You may find it just Here
<https://www.lazarus-ide.org/index.php?page=downloads>

3) Use fpcupdeluxe, which performs an "isolated" installation, not giving a damn about the mess your distro has made with fpc and Lazarus. Just download the binary for your platform, make it executable, select an appropriate installation directory in your user space and launch it. Select the stable versions of fpc and Lazarus, and if you want to test the new features, you may later install a second version in a different folder with the "trunk" versions. You may download fpcupdeluxe for your architecture? from Here
<https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases?after=crosslibs_v1.3>. If you don't see what you need, just click on "Show all 43 assets" to get the full list. I believe that what you need is just a plain fpcupdeluxe-x86_64-linux.

Both in cases 2) and 3) it might complain about some system libraries missing. It tells you the library it needs but it can't know the name of the package in which your distro has included it. It's then up to you to locate and install the necessary packages, either asking apt-get which package provides that library, or asking the web.

Hope that it helps.

When trying to clean out leftover fpc and lazarus files, also search in "/etc" and "~/" ($HOME) for these:
(note that some of these are "hidden")

.fppkg (directory)
instantfpc (directory)
fppkg.cfg
fppkg.bak
fpc.cfg
fpc*.cfg
fp.ini
fp.cfg
fp*.cfg
.lazarus (directory)
lazarus* (directory)

3) Use fpcupdeluxe,...it might complain about some system libraries missing.

Follow the instructions here:
https://github.com/LongDirtyAnimAlf/fpcupdeluxe

The instructions list the common dependencies and provide an example install command for debian like systems:
sudo apt install make binutils build-essential gdb subversion zip unzip libx11-dev libgtk2.0-dev libgdk-pixbuf2.0-dev libcairo2-dev libpango1.0-dev

Debian derivatives based on "stable" ships with relatively old package versions due to its release philosophy (the focus is on stability, not latest features). For example the Lazarus version available for Linux Mint 21.3 via apt is 2.2, which was released more than 2 years ago. I also recommend going the alternative route suggested by Giulano to get the latest up to date versions of fpc and Lazarus.

The Sourceforge page :

https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%203.4/ has these Debian packages :
fpc-laz_3.2.2-210709_amd64.deb
<https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%203.4/fpc-laz_3.2.2-210709_amd64.deb/download> fpc-src_3.2.2-210709_amd64.deb
<https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%203.4/fpc-src_3.2.2-210709_amd64.deb/download> lazarus-project_3.4.0-0_amd64.deb

Installing them should work.

Hey guys!

Firstly, congratulations to anyone who can easily install Lazarus on any distro. I never got it. It's been a very difficult thing in any of the distros I've used.
I really appreciate Lazarus and I love using it, but installing it on Linux is really difficult. At least in my experience. Once again I was suffering even though I was using Linux Mint, a very user-friendly distro. Even with the help of all the kind people here in this group, I couldn't do it. I was about to give up when I remembered to ask chatGPT. So, following his instructions, I finally successfully installed version 3.4.
So I would like to thank everyone here for their collaboration who tried to help.

Greetings from S?o Paulo - Brazil

When I asked it, it hallucinated a lazarus debian repo.

I often hallucinate a lazarus debian repo, even when sober.
