The folder /home/student/LFD259/SOLUTIONS/s_05/EXAMPLES/ is missing from my copy of course material, is there any way I can get a complete copy?
You can try looking directly in the .../s_05/ directory to find the required files. EXAMPLES is just a typo, introduced here in error.
The credentials to retrieve the newer resources version are the same, you can find them in the course material, just as before.
I am also not able to login at https://training.linuxfoundation.org/cm/LFD259/ using my correct credentials and check for newer or complete version.
The new tarball is uploaded. The login to the directory you mention is the same as is mentioned in the book, the one with the username LFtaining you used in exercise 2.1. Check there for the password.
Once you download the new tarball and extract it I would use the find command to locate the file as sub-directories may change, as mentioned in the lab exercise
Please use credentials from the Introduction > Course Resources page to log in.
