I am trying to install packages with this command:

sudo apt-get -f install lib32z1 lib32ncurses5 lib32stdc++6

But I am getting errors during the installation. Error looks like:

pkg-name : Depends: pkg-name (= X.X) but it is not going to be installed

Here are some screenshots:

Errors - 1

Errors - 2

Any suggestions?

    @TONTONFLASH I don't think that is the solution because here apt isn't reporting package not found. instead showing dependency error.

    Bhvya Dhiman, please post your apt-cache policy output to the post editing it. also apt-cache policy gcc-5-base

Those packages have been replaced under the newer multiarch specification, so add :i386 to specify the 32-bit version if you are running a 64-bit system, otherwise APT will assume you want the 64-bit version.

This works for me in Ubuntu 16.04:

sudo apt install zlib1g:i386 libncurses5:i386 libstdc++6:i386

Thanks to comment by TONTONFLASH leading to the other post where another comment by steeldriver gave the necessary hint.

    The packages are same. but if you want to install 32bit packages in a 64bit system, you need to append those. otherwise apt will think you wanted 64bit versions of those packages – Anwar Sep 03 '16 at 17:26

    thanks @Anwar I keep trying to clarify this post and getting distracted by chat >_< is it OK now? – Zanna Sep 03 '16 at 17:33
  • did'nt work @Zanna – Bhavya Dhiman Sep 03 '16 at 19:03
  • OK @BhavyaDhiman I may have to delete my post, but please first try doing dpkg --add-architecture i386 && sudo apt update and let me know the result – Zanna Sep 03 '16 at 19:46
  • does 'nt work , permission denied, and i don't know how to apply chmod +x to this ? @Zanna – Bhavya Dhiman Sep 04 '16 at 09:26
  • @BhavyaDhiman sorry, you need sudo at the start sudo dpkg --add-architecture i386 and then sudo apt update – Zanna Sep 04 '16 at 09:28
  • @BhavyaDhiman you were requested to give the output of apt-cache policy – Anwar Sep 06 '16 at 05:18

1. Enter this command:

sudo apt-get -f install

This is an 'apt' command to fix dependencies ("-f").

2. Then enter this command:

sudo dpkg --configure -a

3. Lastly enter this command (from 'Step 1'):

sudo apt-get -f install

0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

This output indicates that the above did not work
