Why does Eclipse's "Check for updates" not work - Ask Ubuntu

Why does Eclipse's "Check for updates" not work - Ask Ubuntu: "I often the permissions on /opt to 1777 to allow anyone to create packages there. Alternatively I use chgrp users /opt and set the permissions to 1775. This allows members of the uses group to add new packages to /opt."



I set the permissions on /home/kasimcee/Development/adt-bundle-linux-x86_64-20131030/sdk and /home/kasimcee/Development/adt-bundle-linux-x86_64-20131030/eclipse to 1777 by typing:



chmod 1777 /home/kasimcee/Development/adt-bundle-linux-x86_64-20131030/sdk [enter]

chmod 1777 /home/kasimcee/Development/adt-bundle-linux-x86_64-20131030/eclipse [enter]



Then, I ran Eclipse and it gave me an adb error.  I closed it and restarted Eclipse again and it worked!
