Since my SSD is small, I still relegate it to only holding the OS.

So, during Ubuntu install, I created a 60 GB partition for / on my SSD, and a 500 GB partition for /home on my HDD.

However, now I am finding issues such as the one described in this question: Conda update <package>: Permission issues

The accepted answer suggested:

sudo ln ~/anaconda/bin/conda /usr/local/bin/

I had to use a softlink because I was getting an "invalid cross-device link" error if I did not specify the -s for softlink in the command. The following discussion (the very last post) gave me the clue of using a softlink: http://www.linuxquestions.org/questions/linux-newbie-8/invalid-cross-device-link-731268/

sudo ln -s ~/anaconda/bin/conda /usr/local/bin/

Now, I find that I am having an issue that looks superficially similar when using the matlab installer script:

brian@brian-linux:~/matlab-installer$ ls
activate.ini  etc      installer_input.txt  license.txt  sys
archives      help     install_guide.pdf    patents.txt  trademarks.txt
bin           install  java                 readme.txt

brian@brian-linux:~/matlab-installer$ ./install
bash: ./install: Permission denied

brian@brian-linux:~/matlab-installer$ sudo ./install
[sudo] password for brian: 
sudo: ./install: command not found

brian@brian-linux:~/matlab-installer$ bash ./install
./install: line 334: /home/brian/matlab-installer/bin/glnxa64/install_unix: Permission denied

brian@brian-linux:~/matlab-installer$ sudo bash ./install
./install: line 334: /home/brian/matlab-installer/bin/glnxa64/install_unix: Permission denied

What is going on, and how can I prevent such issues once and for all in the future?

This problem occurred because the drive onto which I put /home was partitioned as NTFS. This is not good, and among the known issues it causes is permission issues. See this answer for further detail.
