Unifi Video fails with error after unifi controller is installed on same server

1, Download “jre-8u271-linux-x64.tar.gz” from [SEE ABOVE]

(Or if the above link is no worky, then https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html (you want the JRE! not the JDK, so scroll down a bit on the page for the “Java SE Runtime Environment 8u271” section))

as root (sudo su):

2, mkdir /usr/local/java (if not already exists)

3, cp “jre-8u271-linux-x64.tar.gz” /usr/local/java

4, cd /usr/local/java

5, tar zxvf jre-8u271-linux-x64.tar.gz

6, rm jre-8u271-linux-x64.tar.gz

7, update-alternatives –install “/usr/bin/java” “java” “/usr/local/java/jre1.8.0_271/bin/java” 1

8, update-alternatives –config java (select the number of the newly extracted one, it was #3 for me):

* 3 /usr/local/java/jre1.8.0_271/bin/java 1 manual mode

9, echo “JAVA_HOME=/usr/local/java/jre1.8.0_271” | tee -a /etc/default/unifi

10, reboot and enjoy.
