Hi @donlillard 

Thanks for reaching out.

Initial steps to free ubuntu space are:

1) Get rid of packages that are no longer required

sudo apt-get autoremove

2) Clean up APT cache in Ubuntu

sudo apt-get autoclean

Also you could check witch folders are taking more space by using the following command and removing those you do not require:

for i in `ls`; do du -hs $i; done 

Let me know if you have further questions,

Best regards,

David

Thank you for your reply. I saw those command to clean up and I've also seen accepted solution to go into /boot and remove old img files. However, none of the command run successfully. I cannot remove or clean up any files. Here are the results of these commands.
