I already tried the recovery mode fix and it did not do anything to fix this!!!!!!!



ok so um i get this error. as i said recovery mode does not work and even logging in as admin does not give me the permissions needed to do this. how do i fix and why didn't recovery mode work????

Is the account you are trying to use the first user account created at installation?
If not any subsequint user needs to be added to the sudo group to have privledges.

A link about how things work with root and sudo in Ubuntu, it is not recomended to use "su" to access a root command line.
better to use "sudo -i" See Link:
https://help.ubuntu.com/community/RootSudo

i have tried with both of my accounts. both the one i created and the admin one. both created at install.

i have also tried the recovery mode trick to fix this but still nothing

It's hard to help unless you post exactly what you tried and any error messages that resulted

Is this account the first account created after install? If it's a secondary account you need to add your account to /etc/sudoers

@steeldriver is right. With the current data about your problem ... reinstall. If you don't have superuser privileges, you cannot edit the sudoers file.

Check your group membership:

groups

If sudo is not in the list, try

pkexec adduser donwolfani sudo

[donwolfani]

just tried pkexec adduser donwolfani sudo and it still wont allow sudo.

im a out to try reinstall bit firsy i need to ask about something. if i restore a backup of my entire home folder will this cause this problem again after the reinstall? and if so what file is causing it so i know what not to allow in the backup.

i have to use my home folder as it.is to lengthy a process moving every individual config file for.the.stuff i use to be able do it without messing up one program or another.

just tried pkexec adduser donwolfani sudo and it still wont allow sudo.

But pkexec itself worked? I mean, is donwolfani now member of the sudo group? What does the groups command show? If pkexec didn't work, what was the error message? I guess it was clear, but just to remove any misunderstandings: pkexec works as a poor man's replacement for sudo, you must enter it as is, without sudo.

[donwolfani]

yes pkexec worked im part of the group but it still will not let me sudo after. pkexec worked fine but.then when i tried to sudo anything it gave me the original error all over again.
