AFTER UPDATING UBUNTU LAZARUS COULD NOT BE STARTED (Maybe this can help) lazarus / 1-Linux ---------------------------------------------------------------------- guest63388 · 2018-12-05 13:37 AFTER UPDATING UBUNTU LAZARUS COULD NOT BE STARTED. Hi, Maybe this can help. I've downloaded Lazarus for Linux: 1- fpc_3.0.4-3_amd64.deb 2- fpc-src_3.0.4-2_amd64.deb 3- lazarus-project_1.8.4-0_amd64.deb Then I'd installed (in order 1,2,3) on Ubuntu 18.04.1 LTS and Lazarus WAS RUNNING PERFECT. OBS: When installing the fpc_3.0.4-3_amd64.deb the Installer Packages informed that was recommended to update the fpc_3.0.4-3_amd64.deb. But, I didn't update it. Next day, when updating LINUX, the fpc_3.0.4-3_amd64.deb was updated automatically, AND Lazarus could not be started. AND I COULD NOT RE-INSTALL IT, CAUSE THE INSTALLER PACKAGES DID NOT INSTALL fpc_3.0.4-3_amd64.deb, INFORMING THAT ALREADY WAS INSTALLED A NEW VERSION ON THE SYSTEM. AND BECUASE OF THIS NEW VERSION, ALSO lazarus-project_1.8.4-0_amd64.deb could not be re-installed. So, I had to uninstall all fp by Synaptic and then I could re-install Lazarus again, in the the following order 1,2,3. And after that, I'd search all fp in Synaptic and lock all files to prevent new updating (*). I hope this can help someone. Regards, * Locking with Synaptic Package Manager: Go to Synaptic Package Manager (System > Administration > Synaptic Package Manager). Click the search button and type the package name. When you find the package, select it and go to the Package menu and select Lock Version.
