I program, but also deal somewhat in video and sound, so I thought Ubuntu Studio was a good fit for me. The version of Ubuntu I am using has been upgraded to 20.04.1 LTS on a 64-bit computer. I have tried several ways of doing this, whether through apt-get, or downloading the .deb package from the Lazarus website. In all cases, I am getting package clashes, with warnings that Lazarus be uninstalled. The fpc compiler that is installed without error is apprarently not the right version required for Lazarus, with the right version being deemed "not installable" by my package manager. Also, there were other libraries that could not be installed. Installing the package "lazarus-ide" through apt defaults to version 2.0.6+dfsg-3.
The Pascal compiler that is there now is version 3.0.4+dfsg-23. Currently, according to my system log (dpkg.log), its status is "half-installed". It is possible that it is not the default version and might have been installed with Lazarus. I used dpkg after doing the install through the normal "Software" app provided by Ubuntu failed.
Of course, there is always the source, but that was not compilable either. The error messages seen by this compile were the same errors as with every other version I have tried, going back to version 1 and forward to 2.0.10. Both "make all" and "makde bigide" (after a "make clean") yielded:
