and the list goes on through each package I am missing. Should I dpkg-reconfigure -a ? citation:What does apt-get --fix-missing do and when is it useful?

I have tried sudo apt-get install --fix missing but I return with the original error message at the beginning of this post.

  • Try dpkg-reconfigure -a. If that doesn't work, there should be some package failing with an error (not a dependency error). – saiarcot895 Dec 31 '14 at 03:08
  • Try with this commands, may be fix the pacakge dependency problem

    sudo dpkg --configure -a

    sudo apt-get install -f

    Please include the command which you were executing with its complete output instead of partial output. – g_p Jan 14 '15 at 06:19

I had this error after upgrading from 14.04 to 14.10. After hours researching found the command that saved the day:

$ sudo aptitude install --safe-resolver

From the man page:

--safe-resolver

When package dependency problems are encountered, use a “safe” algorithm to solve them. This resolver attempts to preserve as many of your choices as possible; it will never remove a package or install a version of a package other than the package's default candidate version. It is the same algorithm used in safe-upgrade; indeed, aptitude --safe-resolver full-upgrade is equivalent to aptitude safe-upgrade. Because safe-upgrade always uses the safe resolver, it does not accept the --safe-resolver flag.

This option is equivalent to setting the configuration variable Aptitude::Always-Use-Safe-Resolver to true.
