Upgrade to 18.04 or newer, preferably 20.04. 16.04 lost support a year
ago and will not be supported here.

Here's how the LTS lifecycle goes:

Ubuntu (proper): 5 years (16.04 goes until April 2021)
Ubuntu Flavors (including Ubuntu Studio): 3 years (16.04 lost support
April 2019).

Since 18.04 was not an LTS for Ubuntu Studio, it's only quasi-supported
through the Ubuntu Studio Backports PPA. Ubuntu Studio 20.04 is a proper
LTS, so you should *really* upgrade to that.
