dpkg --configure -a'

[Stormdrainer]

I have been updating my installation of Linux Mint 21. When I try to do this I get an error message saying: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

How do I run dpkg --configure -a. I am a beginner. Could you please spell out each stage I need to go through? Thanks very much.

Also How do I report the item I am asked to report.
Thanks for any help you can give.

You need to use sudo:

Code: Select all

sudo dpkg --configure -a

[Pjotr]

- Launch a terminal window (this is how to launch a terminal window);

- Copy/paste this command into the terminal:

Code: Select all

sudo dpkg --configure -a

Press Enter.

Edit: sleeper12 beat me to it.

Yeah that sudo thing... A beginner friend of mine had the same problem... They should really add that information to the error in the Update Manager...

It's one of those things that (as I recall after looking once) is a case of "a simple matter of programming" (i.e. looks simple on the surface, but isn't).

Upstream thingy with apt / apt-get / dpkg?

Yeah, mostly that the switch to detect if it was run by pkexec is not easy (well, as I vaguely recall -- it's been an absolute age)
