followup of the last post brave was installed, but I got : ELF interpreter /lib64/ld-linux-x86-64.so.2 not found, error 2 when trying to launch it from /usr/local/bin/linux-brave As I had nothing else installed on /compat/ubuntu, I decided to let the script reinstall the ubuntu system : doas ./linux-browser-installer chroot delete (deletes /compat/ubuntu, please don't do this it you have other linux softwares installed in it) doas ./linux-browser-installer chroot create (recreate it with all the dependencies) It runs fine now. I guess the script doesn't check all the needed freebsd & ubuntu packages when it sees that /compat/ubuntu is already installed.
