Help with sudoers file

[brotherhood]

Hi there ,

i have accidentally deleted my sudoers file in /etc.. i managed to get a working sudoers file which is saved on my desktop , ttrouble i can't copy this file into /etc (permission error) . I try rebooting in RECOVERY MODE , but it asking me for username and password , which doesnt exit , since i lost the original sudoers file , so im not even able to log on in recovery mode.
Does anybody know a workaround < i don't want to have to re-install mint

Never ever touch the sudoers file unless you know exactly what you are doing - this is for "gurus"
And you can't accidentally delete it - you must first have removed a lockfile
You use visudo to edit sudoers - nothing else, and you need password for that
Unless you specified a root password you can enter "recovery mode" - if you specified a root password - well - you're done - almost
Boot the live CD and mount the / partition
It should be possible just to copy your backup
But remember
Never ever touch the sudoers file!

Thanks for your help husse ,
i tried what you suggested but i failed big time , so i had to re-install mint again , only took me 20 minutes , im up and running again . although my USB pen drives are not being automatically mounted ? dont know why , but it was working before , i suspect it is something to do with "udf,iso9660"
here's my /etc/fstab

Code: Select all

/dev/sdb1       /media/cdrom0   udf,iso9660 user,noauto,exec 0       0
/dev/scd0       /media/cdrom1   udf,iso9660 user,noauto,exec 0       0



As far as i know the "udf,iso9660" in the third column should be "auto". Do i have to manually change that in vi or something , am i trying not to be adventurous after last night

thanks

Nope, your /etc/fstab is correct.
Do you get any errors when trying to mount a usb pen drive through dolphin,thunar or w/e, ie right click>actions>mount

P.S. Just use any old text editor for editing, it's a damn sight easier than vi, unless you want to learn it ofc

If it is correct , then i don'k know what is going on.
When i plug any USB , i get this error : Cannot mount volume.Invalid mount option when attempting to mount the volume.

Solved ----------- I changed the entry in the third column to "Auto" and it worked like a charm
