I have been using instructions that can be found here for my 14.04 systems. But after running:
sudo add-apt-repository ppa:synapse-core/ppa
sudo apt-get update
I get the following on kUbuntu 16.04LTS:
W: The repository 'http://ppa.launchpad.net/synapse-core/ppa/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/synapse-core/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found
E: Failed to fetch http://ppa.launchpad.net/synapse-core/ppa/ubuntu/dists/xenial/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
If I proceed to install, it will install but not function properly (can't access settings). In kUbuntu 14LTS I would left click the icon in the system tray to change settings. In kUbuntu 16LTS I can right click all the other icons and change settings but not the icon for synapse.
Am I installing synapse wrong in kUbuntu 16LTS? How do I access the settings?
