Until the issue is properly resolved and Ubuntu's Qt packages are updated, I have found that installing the Qt 5.6 libraries from the PPA here https://launchpad.net/~beineri/+archive/ubuntu/opt-qt56-xenial solves this problem.
The libraries are installed to /opt and so they shouldn't interfere with the rest of the system. To use the Qt 5.6 libraries, owncloud can be started as follows: LD_LIBRARY_PATH=/opt/qt56/lib/ /usr/bin/owncloud Note: I am not sure if Qt 5.6 is officially supported by owncloud (there are at least problems on OSX - see here for a discussion: https://github.com/owncloud/client/issues/3449), but for me everything seems to work. This also fixes the issue that the owncloud icon does not appear in the system tray. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572321 Title: owncloud network access is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/owncloud-client/+bug/1572321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
