for a while I have got a prohibition sign in my tool bar. When I click on it I get the message that "my installed packages have unmet dependencies".

My software updater tells me the following:

Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
 The following packages have unmet dependencies:

linux-generic-hwe-16.04: Depends: linux-image-generic-hwe-16.04 (= 4.15.0.58.79) but 4.15.0.58.79 is installed
                         Depends: linux-headers-generic-hwe-16.04 (= 4.15.0.58.79) but 4.15.0.55.76 is installed"

I have been trying to install a new program (opencpn) but I need to fix the problem first.

Could someone help understand the problem?

  • Thanks, I ran sudo apt-get upgrade -f and the prohibition sign disappeared though it seems I still have some problems: at the end of the process log I get W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915 W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915 Processing triggers for dictionaries-common (1.26.3) ...

  • Have you tried the other commands also or just that one – crip659 Dec 4 '19 at 16:52
  • I have also tried sudo apt-get clean with no results, sudo apt-get autoclean with no results and sudo apt-get -f install with the following message: dpkg: error processing package linux-headers-4.15.0-58-generic (--configure): package is in a very bad inconsistent state; you should reinstall it before attempting configuration Errors were encountered while processing: linux-headers-4.15.0-58-generic E: Sub-process /usr/bin/dpkg returned an error code (1) – Larry Golade Dec 4 '19 at 21:57
