unable to upgrade plex

[BlayZin]

since the update 1.15 the upgrade script isn't working anymore (probably because they changed something on their servers)
I get:

Authenticating ... OK
Finding download URL to download ... OK
 ERROR: Unable to retrieve the URL needed for download (Query DISTRO: ubuntu, BUILD: linux-ubuntu-x86_64)
exit

Seems to be fixed now with recent commit!
