After immediately selecting 'Drop into root shell prompt' I found the filesystem was mounted read only, which prevents resetting the password. Choosing the option to remount / as read/write and going back into the root shell prompt enabled the password change. The command to run prior to changing the password is: mount -rw -o remount / share|improve this answer edited Apr 29 '12 at 14:39 Community♦ 1 answered Jan 3 '12 at 23:29 Brandon 1,366172 Thank you, that worked. –Somebody Apr 7 '14 at 16:54 1 even after following these steps it will not accept my password –angela Aug 14 '14 at 15:09 2 Odd. mount showed that / was already mounted as read/write, but mount -rw -o remount / still worked. No idea why. –Hubro Dec 2 '15 at 9:11 Thanks a lot for your help! –Love Jun 13 at 13:53 i am simply one of those idiots who did not read the stdout and forgot to put in the "(current) Unix password" but the password that I want it to be :( –B.Mr.W.

If you want to use chpasswd(8) or usermod(8) you shoould carefully RTFM. Be sure that the given password is compatible with the system configuration. And sudo should apply to the chpasswd command, so you probably want echo 'user:passwd' | sudo chpasswd In your case sudo echo 'user:passwd' | chpasswd the sudo is applied only to echo, which is incorrect. share|improve this answer edited Aug 18 '15 at 13:39 answered Aug 18 '15 at 13:33 Basile Starynkevitch 2,638519 would even make more sense to run the whole thing as root instead of issuing sudo all the time. –Fiximan Aug 18 '15 at 13:40 @Fiximan: this really depends upon the system configuration. On some systems using sudo would be very sensible. –Basile Starynkevitch Aug
