Xenial has libicu55 so I don't think that libicu52 can be added to the Xenial repositories.
May be bugs should be raised against those applications that depend on libicu52 so that they are updated to depend on libicu55? ** Tags added: xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589487 Title: libicu52 not present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1589487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
