Problems installing zextras suites on zimbra 8.7.11 OSE

[Rubelman]

I have a problem on my zimbra 8.7.11 OSE in ubuntu 16.04, when I run zmprov: /opt/zimbra/bin/zmjava: line 56: /bin /java: no such file or directory

I have run several commands but there is no solution to the problem in JAVA.

says the following:

Checking for existing installations ...
Use of uninitialized value in join or string at -e line 1, <> line 1.
