I have installed lazarus (2.0.2) . My operating system is Ubuntu 19.10.Earlier lazarus (lazarus 1.8.x? on earlier ubuntu 18.04) was working well. After some progress in developing my program code I have installed a new version and began receiving some strange results. Lazarus writes that it compiles and builds with "sucess" but is 'unable to run "/home/eugen/aux/lmarka/project1"'
