Totally apologize for not meeting all the standards here. Been using Ubuntu since Nov 2015 and performed two upgrades I'm still a rookie and have not found the exact problem in any Ubuntu searches. Here's the 3 broken dependencies listed in the Synaptic Package Manager under broken Dependencies:

  1. CUPS 2.1.3-4unbuntu0.2 2.1.3-4ubuntu0.2 Common UNIX Printing System(tm)-PPD/driver, support web interface

  2. CUPS-core-drivers 2.1.3-4unbuntu0.2 2.1.3-4ubuntu0.2 Common UNIX Printing System(tm)-PPD-less printing

  3. CUPS-Daemon 2.1.3-4 2.1.3 Common UNIX Printing System(tm)-Daemon

This PC is only used at home as a stand-alone and only connected to the IT. I can still print with no problem, however, since this occurred last week after performing an update. The only problem this causes the inability to perform any updates, which is a serious problem.

I will provide any info you need, but will need step by step help.


This is a bug in a recent CUPS update: cups : Depends: libcups2 (= 2.1.3-4) but 2.1.3-4ubuntu0.2 is to be installed

Solution given in comment 14 is: sudo apt-get install libcups2=2.1.3-4 cups libcupscgi1=2.1.3-4 libcupsimage2=2.1.3-4 libcupsmime1=2.1.3-4 libcupsppdc1=2.1.3-4 cups-core-drivers cups-daemon ghostscript cups-client=2.1.3-4 cups-ppdc cups-filters printer-driver-gutenprint cups-filters

  • Not much info there due to space. I copied terminal cmds and results, but to long to post. Tried to unlock file and then tried kill cmd and reboot per article ubuntuforums.org/showthread.php?t=1853026 – Ronald Railing Mar 31 '17 at 12:20
