This behavior is consistent with Ubuntu Software Centre. Canonical works with third-party software providers to provide payment and hosting for commericial software in the partner repository. In Ubuntu 16.04 LTS, this is being replaced by the Ubuntu App Store which powers the snap repository's backend.
While the command line tools provide access to free-of-charge snaps without issue, the Ubuntu Software store uses Ubuntu One to handle payment processing and order history (so that previous purchases can be downloaded and installed on any number of systems that you own). So this is an implementation detail that matches the behavior of the software being replaced by Ubuntu Software. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581713 Title: Ubuntu Software asks for an Ubuntu Single Sign-On account to remove a snap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1581713/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
