E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I don't know what that means. Please tell me what I should do next. Thanks in advance for your help.
Installing a package with apt in a server failed with a "No space left on device" message. I removed a few hundred MB and ran sudo dpkg --configure -a again, just to get another "No space left on device" error.
