Hi,
1. Get to
https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%202.2.2/From there download:
lazarus-project_2.2.2-0_amd64.deb
fpc-laz_3.2.2-210709_amd64.deb, and finally
fpc-src_3.2.2-210709_amd64.deb
Respective files will be downloaded to the directory ~/Downloads
2. Open the command prompt and get to the download directory
cd ~/Downloads
3. From the command prompt install downloaded files one by one in this order:
fpc-laz_3.2.2-210709_amd64.deb
fpc-src_3.2.2-210709_amd64.deb
lazarus-project_2.2.2-0_amd64.deb
The simplest way to install a .deb file is with dpkg eg
sudo dpkg -i <deb_file_name.deb>
4. It is not unusual that installation will not be complete after this, with a number of support .deb packages not been installed. In this case just follow what
dpkg prompt's you to do. It works.
kind regards
s
