Kopano Core 8.2.0 final is now available

  • Kopano

    As the name implies Kopano Core sits at the heart of every Kopano environment and is therefore a key figure in our promise to deliver stability and extendability of Kopano’s proven communication platform. In version 8.2 we introduce improvements on SSL hostname verification, LDAP configuration organisation, migration tools and many more enhancements. Please read this release announcement carefully, since it contains important information for upgrading to this latest major version.

    Hi @Gerald ,

    thanks for bringing this to my attention. The current version of the script is missing the she-bang and therefore has to be executed like python /usr/sbin/kopano-search-upgrade-findroots.py

    I have created https://jira.kopano.io/browse/KC-553 to fix this for the next iteration of the packages.

  • @fbartels

    Hi, when can we expect the Update to be available in Univention UCS App portal to Update our UCS installations ?


  • Kopano

    Hi Christian,

    the update to enable 8.2 compatibility in Univention has been uploaded last week and is currently awaiting approval. The update does bring the ability to easier update the Kopano Core packages through our official repositories, but no actual packages. Once this has proven itself the same mechanism will be rolled out for the other Kopano Univention apps .

  • Great sounds great to have the ability to use the Kopano repos in future !!!
    thanks & rg

  • Hi @fbartels,

    We upgraded this morning to 8.2.0 - final and noticed a warning we have never seen before in server.log

    Mon Feb 20 08:03:55 2017: [warning] Object not found unknown user "Everyone": Everyone

    The upgrade itself went without a hitch and we also executed python /usr/sbin/kopano-search-upgrade-findroots.py … so no issues there.

    Also, can you look into the possibility of including an archive of the source at the time of release (for both stable and pre-final/beta releases) in the supported download area as we are compiling our own mapi version against remi’s php56 on Centos 7?

    Finally, we like to know why Kopano’s mapi.so version is way smaller in size than the version we compile - ours is 1.7MB and Kopano’s is ~ 400KB… We used the instructions at https://documentation.kopano.io/kopanocore_administrator_manual/installing.html?highlight=compile as reference. Again, this is on the latest Centos 7 release with only remi’s php56 and MariaDB 10.1 installed - what’s your secret sauce?

    As reference, we use:

    ./configure --enable-epoll \ 
    --enable-unicode \
    --disable-static \
    --with-userscript-prefix=/etc/kopano/userscripts \
    --with-quotatemplate-prefix=/etc/kopano/quotamail \

    We previously used --enable-swig, --disable-testtools, --enable-python, --enable-tcmalloc in addition to the above, however, the configuration script gave a warning that these options were no longer recognized so we dropped them.

  • Fyi, my upgrade went well, just “yum upgrade”, very slick, BRAVO!

  • @fbartels

    When will this be available as it now some weeks later ?



  • Kopano

    @externa1 we have a bit of a disagreement on how the repository integration for Univention should be achieved. Hopefully we have new idea until the end of the week (as Univention is also quite busy with their upcoming release).

  • @fbartels
    thanks :)


  • @externa1 said in Kopano Core 8.2.0 final is now available:


    any news on this? I try to avoid answers from the support alla “please update to latest release” and I can’t do this :(

  • Kopano

    @Atomius sadly Univention is still busy with their upcoming release. If you’re feeling adventurous, then you can activate their test appcenter with the following command:

    ucr set appcenter/index/verify=no update/secure_apt=no repository/app_center/server='appcenter-test.software-univention.de'

    This will then give you Z-Push 2.3.5 and the Kopano App with Reposupport for 8.2.x.

    EDIT: or less invasive. Just add the following line to /etc/apt/sources.list, then do an apt-get update && apt-get upgrade.

    deb http://repo.z-hub.io/kopano4ucs/Univention_4.0/ /

    Afterwards you can follow https://wiki.z-hub.io/display/K4U/Updating+Kopano+packages+directly+from+the+Kopano+download+server

  • @fbartels

    It’s working with ucr set. Now I’m a real Betatester instead of half one ;)

    Core shows:


    Is that similar to 8.2?

  • Kopano

    @Atomius thats just the version of the “app”, after you have enabled the repository like explained on the wiki page, there should be a package update which brings you to 8.2.1 (you can see the actual version in the WebApp settings).

  • Everything went fine. System now runs 4.1-4 errata360 (after disabling fetchmail repo)

    Kopano Core:

    Thank you for your support ;)

  • Kopano

    @Atomius please keep your posts in English.

    I also got the news a few hours ago, that the update is now officially available.

  • @fbartels

    sorry for that, it’s a bit confusing as the support team answered in German :D changed that.

    No problem, I think this situation would repeat often, as the development is faster than the audition ;)

  • Hello,

    @fbartels since the changelog mentions the “Extended and enforced SSL hostname verification” with additional configuration needs I’d like to know if UCS is also affected.
    Since the UCS Apache proxies the connections, correct?
