Hi fbartels,
thanks for your hints. I had a test license. But this update did not work and the support could not help. So I had to completly remove every tick in the settings (as explained in https://kopano.com/blog/staying-up-to-date-with-kopano-releases-on-ucs/) otherwise this UCS memberserver failed updateing/upgradeing.
dpkg -l | grep kopano-webapp
shows the output version:
kopano-webapp 3.5.14.2539+111.1
Is this the latest version, that I can get without a subscription?
Kind regards and thanks in advance
