From man usermod:
Note: if you wish to lock the account (not only access with a password), you should also set the EXPIRE_DATE to 1.
I have recently installed StackApplet and I want to add my account to it. However, I can't do so as I am unable to select a site properly. See this screenshot:
When I press on the option Site nothing appears. Instead, a blank dock appears displaying nothing. Clicking on the dock causes it to disappear.
I have accidentally typed my name wrong when I created the administrator account. Although I managed to change the user name at the login screen, I am unable to rename the /home/oldusername to /home/newusername. I tried most of the online tutorials, and it failed.
The code I tried was this:
usermod -l newusername -m -d /home/newusername oldusername
But the output is:
cannot lock /etc/passwd; try again later.
How can I fix the issue and change the folder to newusername and expect all the applications to work as before?
Sometimes I have friends in my house that want use my computer. How can they use a guest account without typing a password?
I want Ubuntu to ask for my password when I log in but not lock me every time I am away for 5 minutes.
How can I disable the automatic lock?
