Platform: virtual private server
amd64,
debian 8 "jessie" (with jessie-backports)
openjdk-8-jdk 8u121-b13-1~bpo8+1 (from jessie-backports)
(the old VM has version 8u111-b14-2~bpo8+1)
karaf-4.0.7
I am trying to move my application from my old VM, where it runs, and on
to a new VM where it won't start even though all of the important parts
I can think of, are the same (listed above, under platform).
The feature installation fails with an error message:
karaf@root()> feature:install ukelonn-db-postgresql
Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=ukelonn-db-postgresql; type=karaf.feature;

Does anyone know what might be wrong?
I get no such error message on the old VM. There the feature just
installs. I get no such error on my desktop, also amd64 (Intel i5,
"skylake"), also running debian 8 with stuff from jessie-backports.
I have searched the karaf.log file but it doesn't say anything more than
the error message.
Is the difference in java version significant? (1.8_121 where it fails,
1.8_111 where it doesn fail)
On the new VM karaf complains about a missing JAVA_HOME:

JAVA_HOME not set; results may vary
On the old VM there is no complaint about a missing JAVA_HOME.
The JAVA_HOME variable isn't set on either machine.
Is the missing JAVA_HOME message significant?
This is my application:
https://github.com/steinarb/ukelonn/tree/using-vaadin
(ie. the "using-vaadin" branch).
This is what I've done, so far, on the new VM:
1. Install openjdk-8-jdk with apt-get, from jessie-backports
https://packages.debian.org/jessie-backports/openjdk-8-jdk
2. Install maven 3.3.9 with apt-get, from jessie-backports
https://packages.debian.org/jessie-backports/maven
3. Install karaf 4.0.7 from a .deb package created by this script
https://github.com/steinarb/karaf-deb-packaging
This deb package creates user karaf, with group karaf and the home
directory /home/karaf and no login shell
4. I've cloned and built my project as user karaf with the following
commands:
/bin/su -s /bin/bash karaf
cd
mkdir git
cd git
git clone https://github.com/steinarb/ukelonn.git
cd ukelonn
git checkout using-vaadin
mvn clean install
After the commands, the /home/karaf/.m2/repository contains the
bundles built by the project, as well as the dependencies
5. I've logged into the karaf shell with ssh:
ssh -p 8101 karaf@localhost
6. I planned to do the following commands, but the first
feature:install failed:
feature:repo-add
mvn:no.priv.bang.ukelonn/ukelonn.karaf/LATEST/xml/features
feature:install ukelonn-db-postgresql
feature:install ukelonn
The feature file added by repo-add, looks like this:
