Unmet dependencies using aptitude to install bind9

  • 772

I am getting error while trying to install bind9 on ubuntu 12.04 I did 

sudo aptitude install bind9


The following NEW packages will be installed:
  bind9{b} 
0 packages upgraded, 1 newly installed, 0 to remove and 1 not upgraded.
Need to get 336 kB of archives. After unpacking 962 kB will be used.
The following packages have unmet dependencies:
 bind9 : Depends: libbind9-80 (= 1:9.8.1.dfsg.P1-4) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is installed.
         Depends: libdns81 (= 1:9.8.1.dfsg.P1-4) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is installed.
         Depends: libisc83 (= 1:9.8.1.dfsg.P1-4) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is installed.
         Depends: libisccc80 (= 1:9.8.1.dfsg.P1-4) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is installed.

         Depends: bind9utils (= 1:9.8.1.dfsg.P1-4) but it is not going to be installed.

The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     bind9 [Not Installed]

    The problem is rather simple, somehow you installed a superior version of some of the bind dependencies that are not in the main repository. The way to solve it is to make aptitude to downgrade the packages.

    sudo aptitude update
sudo aptitude install bind9=1:9.8.1.dfsg.P1-4 libbind9-80=1:9.8.1.dfsg.P1-4 libdns81=1:9.8.1.dfsg.P1-4 libisc83=1:9.8.1.dfsg.P1-4 libisccc80=1:9.8.1.dfsg.P1-4 libisccfg82=1:9.8.1.dfsg.P1-4 liblwres80=1:9.8.1.dfsg.P1-4
sudo aptitude safe-upgrade

    If you want to make aptitude solve the dependencies himself, you only have to say n to the question:

    Keep the following packages at their current version:

    1) bind9 [Not Installed]

    Accept this solution?

    Then aptitude will offer another solution, being the important where it says "downgrade". As you can see the solution offered keeps bind9 uninstalled, that's why you end without installing it.

    how did you reached at conclusion that the packages I have are not in repositories is it because of .dfsg.P1 extensions or some thing else?

    apt-cache policy lists the origin and version of any packages, which in your case were only in /var/lib/dpkg/status, which is interpreted as that the package only exist locally and in no other repositories. A example of a package that indicates is in both the repositories and locally:

    apt-cache policy aptitude
aptitude:
  Installed: 0.6.8.1-2ubuntu2
  Candidate: 0.6.8.1-2ubuntu2
  Version table:
 *** 0.6.8.1-2ubuntu2 0
        500 http://archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
        100 /var/lib/dpkg/status

    As you can see, the same version is in /var/lib/dpkg/status and in the Ubuntu repositories.

  2. Press n when it asks if you accept the solution (Y/n/q). Aptitude will offer a new solution, and then hit y. It will likely work!

    Cheers,
