Hey this PREY app wont install on my Ubuntu 18.04 OS using "prey_1.7.5_1386.deb and it says it is missing some dependencies. But the worst part is that when I executed "sudo apt-get upgrade -f" to fix the errors it tried to remove sudo and my Webmin install.
Removing sudo (1.8.21p2-3ubuntu1) ...
You have asked that the sudo package be removed,
but no root password has been set.
Without sudo, you may not be able to gain administrative privileges.
If you would prefer to access the root account with su(1)
or by logging in directly,
you must set a root password with "sudo passwd".
If you have arranged other means to access the root account,
and you are sure this is what you want,
you may bypass this check by setting an environment variable
Refusing to remove sudo.
