Unity web player download fail

ERROR: Downloading of wine-x64-unity3d-installer failed multiple times. Please check:
[install-dependency]
[install-dependency] * that your internet connection is working properly
[install-dependency]
[install-dependency] * and that the plugin database is up-to-date. To update it just run:
[install-dependency] sudo pipelight-plugin --update
[install-dependency]
[install-dependency] If this doesn't help then most-likely the download URLs or checksums
[install-dependency] have changed. We recommend to open a bug-report in this case.
