[horde] Horde installation with PHP7

[Melkor Lord]

Hi,

Using Ubuntu server 16.04, I currently can't install Horde the way I intend
because of dependency issues.

Shell# pear install -B horde/ingo
[...snipped...]

No valid packages found

Could it be possible to update the depencies tree? IMHO there's little
chance that Horde is really incompatible with PHP7, at most I think about
deprecated functions/methods. At least, I'd like to try.

For info, the official Ubuntu packages have fixed the dependencies so this
should not be a big issue. The packages are a bit outdated, hence the
manual install.
