I was installing the Bitnami Odoo 11 module on my AWS t2.nano. It’s a fresh instance with a 1gb swap partition and 500mb of hardware RAM. This should be enough to run most if not all Bitnami packages. However when I was installing the package ontop of Bitnami LAMP I got error messages.
Unable to create symbolic link
TLDR: You probably need to restart the machine and install from the command line.
I tried a variety of things to resolve the error
confirm that you have enough memory
confirm that you have sufficient disk space
confirm that the user can create symbolic links in the location mentioned by bitnami
link -s bitnami_source bitnami_target
If you are able to do all these things a simple restart fixed the problem for me. You can run the installed from the command line without giving resources to the GUI which also seems to help. I actually found it a little nicer than the GUI interface.
