Try again. Trying to update Firetools and Firejail in Linux Mint 19. Get following message: An unhandlable error occured. There seems to be a programming error in aptdaemon,the software that allows you to install/remove software and to perform other package management related tasks. I'm also unable to close the package installer as it remains frozen on screen after clicking on install package button.
I'm currently using firejail_0.9.64.4_1_amd64 non-apparmor version. Would there be any harm in installing the latest version of "Firejail apparmor version"? Or should I uninstall FJ first?
