Attempt to add bamboo remote agent causes error with chmod

[yogesh_devi]

Hello , I am running Atlassian Bamboo version 7.1.1 build 70117 - 23 Jul 20.

I am trying to Add a Ubunto 20 remote  build agent 

When I try  running the agent installer jar as show below 

java -jar atlassian-bamboo-agent-installer-7.1.1.jar https://atlproxy.ucalabs.com/bamboo/agentServer/ 

I get following error . 

Installing file: /generic/lib/wrapper.jar to: /root/bamboo-agent-home/lib/wrapper.jar

 Also , please note that this error is agonstic to JDK used. I tried switching between JDK 1.8 and the Java 14 JDK on Bamboo agent - but this error remains the same across JDKs

I could resolve this with following sequence although sadly I am unable to nail the exact reason that was causing this error - 

1 ) Completely remove the old bamboo agent home  ( old home directories are cause of most problems  - and make sure the old home does not exist in any path ) 

2) Make sure you use right supported version JDK ( in my case )  - 

java version "1.8.0_60" - Earlier I had used JDK14 that isnt supported 

3) Make sure you are using the appropriate jar 

4) Specify the bamboo agent home explicitly in the registration command using the -Dbamboo.home  ( The default command displayed does not include this option) -

java -jar -Dbamboo.home=/home/bamboo/bamboo-agent-home atlassian-bamboo-agent-installer-7.1.1.jar https://atlproxy.ucalabs.com/bamboo/agentServer/

5) Run this as a bamboo user with right shell ( I used bash to make it work  )
