I am trying to upgrade eclipse to the latest version, neon.

I have downloaded the tar.gz and untarred it. I open the directory and there is a file eclipse-inst.

If I don't run it as sudo it fails to install. If I do run it as sudo it tries to set everything into areas for /root and then I can't access them later.

For example, I "pinned" the apparent "launcher" button but clicking it now achieves nothing.

The only way I can seem to get back is as a super-user.

Trying to run it otherwise gives me:

The Eclipse executable launcher was unable to locate its companion shared library`

I can run it with 

sudo eclipse

but I don't want to have to run it as a super-user.

When trying to install on my own account I get:

You must change user owner and permissions of the installer. If the problems persist, try the same on the installation folder and files:

sudo chown <yourUserName> <file>
sudo chown -R <yourUserName> <folder>
sudo chmod 0644 <file>
sudo chmod 0644 -R <folder>

Where <yourUserName> is your user name, and <file/folder> the file or folder to process.

Try to install Eclipse on a separated folder in your Home folder, for example: /home/$USER/Programs/Eclipse

  • Firstly, the installer itself is in my own user name and owned by me. Secondly, I don't really want to install it under my home directory. – CashCow Aug 3 '16 at 17:09
