So I decided to install Lubuntu today (it's the 18.04 release with the silly beaver) on my old Asus laptop using an external HDD with a Windows bootloader booting an ISO from disk to launch the live system and install Lubuntu. The install went swimmingly, but the very first thing I try to execute (sudo) gives me this error:

/usr/bin/sudo must be owned by uid 0 and have the setuid bit set [duplicate]

I know this error has been posted more times than I've been around the sun, but whatever I do, whatever I try, nothing remedies it. I tried the permission tricks such as:

chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo

only to have crap thrown in my face yet again, despite me executing this from the root recovery console.
Not only this, but I keep getting permission errors randomly. For example, I try to install a package and I get this random error about permissions on a file in /usr/lib (don't quote me on that) which also complains about invalid permissions.

Eventually, I got the time to do a reinstall, and the exact same issue occurs. So I redownloaded Lubuntu and tried again, only to have the exact same thing happen again.

To be noted: I cannot get online whilst in Lubuntu because I can't install the Atheros drivers due to this fault, so I can't do things like apt-get unless I physically connect my modem into the wall, so that's out of the question.

I verified the ISO and there's no issue there, so I'm lost as to what the cause could be.

Any, and I mean ANY suggestions gladly appreciated.

  You haven't told us what release of Lubuntu you are referring to. I also get the feeling you are talking about a VM installation (not real hardware). Did you verify your download? and then install media? prior to install. You weren't specific about atheros and I don't know what wiki (help.ubuntu.com/community/WifiDocs/Driver/Atheros etc) or online searches & questions on this site you tried to fix so I'll skip that. You also list chown root:root which won't work as listed unless you're logged in as root. You're heavy on story & light on detail in my opinion.

  Sorry for the ambiguity. Hopefully the post is a bit better now. I am using real hardware and not a virtual machine. You can ignore the part about Atheros for now since it's not part of the issue.

  To be noted; I did run chown root:root as a root user, since that's what the terminal prompt in the recovery mode uses. The command did not give any verbose output so I assumed it executed fine.
