Why won't my linux update?

Question

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.



Thats what it says when i try to do the auto update and it wont let me do anything else until its installed. When i try to run the program through the terminal it says requested operation requires supervisor permission or something like that. What do i need to do?

Answer 1

update - Linux Command - Unix Command

This command is used to bring the application ``up to date'' by entering the event loop repeatedly until all pending events (including idle callbacks) have been processed.



If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed immediately.



The update idletasks command is useful in scripts where changes have been made to the application's state and you want those changes to appear on the display immediately, rather than waiting for the script to complete. Most display updates are performed as idle callbacks, so update idletasks will cause them to run. However, there are some kinds of updates that only happen in response to events, such as those triggered by window size changes; these updates will not occur in update idletasks.



The update command with no options is useful in scripts where you are performing a long-running computation but you still want the application to respond to events such as user interactions; if you occasionally call update then user input will be processed during the next call to update.

Answer 2

type "su" in the terminal, put in your root/supervisor password and then run the dpkg as instructed in your error report.

Hope this helps.

Answer 3

run as super user...i think the command is su - (enter) then enter root password...do that before running the command.
