Unable to install mbstring Ubuntu 16.04

Question

When I try to install php7-mbstring I get the following error:

The following packages have unmet dependencies:
php7.0-mbstring : Depends: php7.0-common (= 7.0.8-0ubuntu0.16.04.3)
but 7.0.13-0ubuntu0.16.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.

I tried what is advice here: How do I resolve unmet dependencies after adding a PPA?. But it did'n work... Any advice ?

Thanks !

Same problem... I think my system is not getting the right version of mbstring. But the package for 7.0.13 exists here : https://launchpad.net/ubuntu/xenial/armhf/php7.0-mbstring/7.0.13-0ubuntu0.16.04.1 — Yo Deux, Jan 03 '17 at 11:23
Did you do sudo apt -f install or you did sudo apt-get -f install ? — George Udosen, Jan 03 '17 at 11:25
Yes I tried all of these already. Also removed and reinstall php7 — Yo Deux, Jan 03 '17 at 11:26
If I understood you correctly, you installed PHP from an external/third-party repository. Note that the PHP repository has now been added to Ubuntu 16.04 so you need not add a repository in order to install it. Try to uninstall and remove the PPA you added then install using: sudo apt-get install php . Hope that helps :) http://askubuntu.com/a/705893/476968 — Tshilidzi Mudau, Jan 03 '17 at 11:57
I finally managed to fix the problem. My source.list did not have XENIAL PROPOSED enabled, and the mbstring package for php 7.0.13 was on this repo. I added it to sources.list and then ran apt-get update && apt-get upgrade and it worked like a charm :) Thanks all for your help — Yo Deux, Jan 03 '17 at 12:44

Finally, I managed to resolve the issue by searching for the package on Ubuntu depository.

The php7.0-mbstring for php 7.0.13 was on the proposed repository that wasn't in my source list

So I edited my sources.list in /etc/apt/sources.list by adding

deb http://archive.ubuntu.com/ubuntu/ xenial-proposed restricted main multiverse universe

then run apt-get update and then apt-get install php7.0-mbstring

Worked fine !
