the following packages have unmet dependencies

When you’ve removed all packages, try installing the one that caused the problem in the first place, and see what happens. The -dry-run parameter makes sure you are informed of whatever happens next. ( PACKAGENAME is the package you’re trying to remove). To remove a held package, sudo apt-get remove -dry-run PACKAGENAME If it exits with X not upgraded at the end, where X is the number of held packages, you will need to delete them one by one. Then (if pb): sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgradeĪnd see if it fixes the issue. Method 5: Eliminate any held packages sudo apt-get -u dist-upgrade

Method 4: Clean the package database sudo apt-get clean Once it’s done running, try installing the software again.

Press Alt, Ctrl and T simultaneously to open a Terminal, and type in sudo apt-get update

Click the list of servers where it says “Download from”, and choose.

In the Ubuntu Software tab, make sure that all the repositories (main, universe, restricted, multiverse) are enabled.Method 3: Make sure that the restricted and universe repositories are enabled and try a better server software-properties-gtk This will try to install the package via aptitude instead of apt-get, which should potentially fix the unmet dependencies issue. Where PACKAGENAME is the package you’re installing,Īnd press Enter to execute it. Method 2: Use Aptitude sudo aptitude install PACKAGENAME Method 1: Use the -f parameter (I know you already did that, but I gather everything here altogether) sudo apt-get install -f I have no idea if it is still relevant for you to get help on this, but here is a summary of the things one could do to help in such situation Try 'apt-get -f install' with no packages (or specify a solution). Libnih1 : PreDepends: libc6 (< 2.16) but 2.17-0ubuntu4 is to be installedĮ: Unmet dependencies. Libc6-dev : Depends: libc6 (= 2.15-0ubuntu10.5) but 2.17-0ubuntu4 is to be installed Libc-dev-bin : Depends: libc6 (< 2.16) but 2.17-0ubuntu4 is to be installed The following packages have unmet dependencies:Īrping : Depends: libnet1 (>= 1.1.2.1) but it is not going to be installedĭepends: libpcap0.8 (>= 0.9.8) but it is not going to be installed You might want to run 'apt-get -f install' to correct these:

Of course just sudo apt-get -f install does not work, same error.
