How to run JabRef on Ubuntu 15.10

When you install JabRef 2.10 on Ubuntu with apt-get install jabref , after that if you run it, jabref never load.
If you go to the CLI, you can see this as follows:

log4j:WARN No appenders could be found for logger (org.java.plugin.ObjectFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Found 2 plugin(s):
  - net.sf.jabref.export.misq (jar:file:/usr/share/jabref/JabRef-2.10.jar!/plugins/net.sf.jabref.export.misq/plugin.xml)
  - net.sf.jabref.core (jar:file:/usr/share/jabref/JabRef-2.10.jar!/plugins/net.sf.jabref.core/plugin.xml)

The problem is associated with java version. Probably, you have a java version above 6 (oracle java 7 or 8). One solution is install a lower version like version 6.
The other solution is download the lastest version compatible with your java version.

wget http://tenet.dl.sourceforge.net/project/jabref/v3.2/JabRef%20Version%203.2.tar.gz
tar xzvf JabRef\ Version\ 3.2.tar.gz

or download it from github
git clone https://github.com/JabRef/jabref

Now, to run JabRef you need to execute ./gradlew run inside the jabref folder
If you want to create a .jar, you need to execute ./gradlew releaseJar
The jar file will be created in build/release folder
Now, you can execute: java -jar JabRef-3.2.jar



If you are using openjdk, you need change it to oracle binary with this command:
sudo update-alternatives --config java

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
