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.
