Ubuntu upgrading - mount /tmp as noexec error

Error:

     Error : mount /tmp as noexec error

Reason:

While upgrading Ubuntu it stores the temporary files in temp directory and tries to execute from the same location. By default, /tmp directory doesn't contain execute permission for security reasons. So that it can't be start from the location /tmp.

Solution:

For while, give execute permission to /tmp and run the upgrade once.

Run the below command to do the same.

    mount -o remount exec /tmp
