I reset my password in ubuntu 12.04. I got "password reset successfully" message.But when I try install/ unistall softwares, I get "worng pawwsord" message.
Why it is so?
Do this in terminal
passwd
you can change the password for the account you are currently logged in
for changing other users password do
passwd <username>
the problem with yours maybe your caps lock was on or mistyped your password.
If unable to reset your password or lost it do the following:
Boot into recovery mode
then select 'root'
then enter command
mount -o rw,remount /
then do
passwd username
this resets the password for the specified account
if you have forgotten the username as well do
ls /home
and the list of users show up
reset the password by entering the above mentioned command
then enter
exit
and select resume from the recovery options menu then ok
