My Intellij version is 12.1 and new version is 12.1.4 so I want to update it but after dowloading new file it can not proceed because of file permission denied. Can any one tell me how to change permission so I can update my Intellij?
Had the same issue with Idea IntelliJ 2016.2
You should set the user and group of your idea folder to yourself. (or a group that you share with other users, if you need)
In my case, it was because some files in idea were assigned to root:root, and I didn't see the point.
So I ran:
sudo chown -R jcharlet:jcharlet /opt/idea-IC-162.1121.32
