Hi,
I’m receiving the following error when installing on Ubuntu 16.04:
root Ceres:/etc/apt# sudo apt-get install openproject

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
@ openproject : Depends: libevent-extra-2.0-5 but it is not going to be installed@
@ Depends: libmagickwand-6.q16-2 but it is not installable@
E: Unable to correct problems, you have held broken packages.
I’ve reverted to the default sources.list in Ubuntu, ran apt-get update and apt-get upgrade, and then followed the installation instructions at https://www.openproject.org/open-source/download/packaged-installation-guide/. Still get the same error. Is the OpenProject repository specified correctly above?
The result of apt-get update that I ran before trying to install OpenProject returned:

You seem to have held packages related to some of the dependencies of OpenProject.
Can you post the output of dpkg --get-selections | grep hold ?
Best,
Oliver
Good question, Oliver. I should have also specified: dpkg --get-selections | grep hold returns nothing
What happens when you excplicitly try to install apt-get -V install libmagickwand-6.q16-2 ?
Explicity install onf libmagickwand returns no installation candidate:
rootCeres:/etc/apt# apt-get -V install libmagickwand-6.q16-2@

Package libmagickwand-6.q16-2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libmagickwand-6.q16-2' has no installation candidate

The following packages have unmet dependencies:

Weird. I have no further clues on why that happens. I’ve rolled a new 16.04 VM and can install 6.0.5. just fine. :-/
Hello,
I have just met similar problem on my fresh Debian 9.1 Stretch.
In my case it seems that package libmagickwand-6.q16-2 but it is not installable. apt-cache search libmagickwand returns among other libmagickwand-6.q16-3 to be available. Probably adding some apt options to get older packages would solve my issue or maybe you have apt repositories dedicated to Debian 9?

Quoting #debian on Freenode. I’m about to deploy new VM with Jessie specifically for OpenProject needs but it would be extremely nice if your Debian repository maintainer supported the latest stable release of Debian and Ubuntu. :-)

On debian 9.1 stretch i need to install libmagickwand-6.q16-2 but only version libmagickwand-6.q16-3 is available in official repos thus openproject fails on dependencies. my │ | question is how to install old package on debian stable in this case. the pkg_name=version style won't work in this case I believe. or maybe it's wiser to do all the job in a schroot │ | environment? any suggestions/pointers are │22:08:09 P4 | welcome very much, please. :-) |22:12:57 somiaj | P4: usually when a package changes from a -2 to a -3 there is an ABI change.

My suggestion if you are using stretch is to build the software to use stretch libaries │22:23:14 P4 | thanks somiaj for your answer. i will probably just deploy another VM to avoid issues.
