[PLUG] Adding admin account back to sudoers

["Eric H. Johnson" <ejohnson@camalytics.com>]

Hi all,

 

This happened to me the last time I ported accounts to a new machine, and I cannot figure out what I did to fix it. Both the old and new machines are running Ubuntu 16.04. After porting all of the user accounts to the new computer, I lost the use of sudo in the administrator account. If I try to use sudo, I get the error that the account is not in sudoers. I booted to recovery mode, mounted the drive read/write, and tried:

 

adduser administrator sudo

 

Which said “administrator is already a member of the sudo group”.

 

I checked /etc/sudoers, and it agrees with what my source (http://www.psychocats.net/ubuntu/fixsudo) says it should say.

 

Another source said to try:

 

sudo usermod –a –G sudo administrator

 

The command ran without error, but did not fix the problem.

 

Any ideas?

 

Thanks,

Eric
