Hello and thank you for filling this bug report. I expect this is a problem with your mirror.

Can you provide `apt-cache policy php7.0-mbstring`?

Should I remove the gandi mirrors ?

Ok, this is an odd (to me) mix of repositories. Do you have a
xenial-updates/unverse entry in source.list? php7.0-mbstring is in
universe, while php7.0-common is in main.

[daamien (damien-taadeem)]

these repositories were defined in the default installation provided by the hosting company (gandi.net)

and yes universe is in the source list

/etc/apt$ cat sources.list
deb http://archive.ubuntu.com/ubuntu xenial universe

[daamien (damien-taadeem)]

The problème remains if I switch to the official repos :

deb http://fr.archive.ubuntu.com/ubuntu/ xenial main restricted universal
deb http://security.ubuntu.com/ubuntu xenial-security main restricted universal
deb http://fr.archive.ubuntu.com/ubuntu/ xenial-updates main restricted universal

I check the php7.0-mbstring package here :

https://packages.ubuntu.com/fr/xenial/php7.0-mbstring

And it says the package depends on php7.0-common (= 7.0.4-7ubuntu2)

which is similary to my apt install error message :

php7.0-mbstring : Depends: php7.0-common (= 7.0.4-7ubuntu2) but 7.0.18-0ubuntu0.16.04.1 is to be installed

I specifically asked if you had a xenial-updates/universe. The above
is for the *release* pocket of xenial, not xenial-updates. If you do
not have a xenial-updates repository for the universe pocket, then you
can easily get into situations like the above (that is, it appears you
have a xenial-updates repository for main (from which php7.0-common
come) but not for universe (from which php7.0-mbstring comes).

Is the sources.list file localized? "universal" vs. "universe"

Did you run apt-get update first?

I do not know why the output is like that, but there is no red dot
next to this dependency:
>

which means it is not a dependency. Looking on xenial, correctly up to date:

$ apt show php7.0-mbstring
Package: php7.0-mbstring
....
Version: 7.0.18-0ubuntu0.16.04.1
Provides: php-mbstring
Depends: php-common (>= 1:33), ucf, php7.0-common (=
7.0.18-0ubuntu0.16.04.1), libc6 (>= 2.14)

I'm 99% sure this is indicating you are trying to install a
php7.0-mbstring from the xenial release pocket (universe component)
and have php7.0-common from the xenial updates pocket (main
component).

[daamien (damien-taadeem)]

yes 'universal' was a typo from me. Sorry about that.

You are right. It's an issue with the mirrors provided by the hosting company.

This is not a bug, you can close this report.

Thanks a lot for your help and sorry again
