I am trying to install Ubuntu 16.04 onto an external SSD that will be booted from when plugged into my 2013 MacBook Air. I am using 16.04 because I will be using the kinetic version of ROS.
I am following this Medium tutorial.
I am in the section titled Fixing the EFI Partition and I am trying to enter the code:
$ sudo add-apt-repository ppa:detly/mactel-utils
When I enter this into the terminal, It gives me an error that says something like
"~detly" user does not exist.
I have done some of my own research and I believe I am unable to execute this command because I am not connected to the internet. The other issue I am having is that I am unable to connect to the internet.
When I click the network drop down menu, the enable networking option is checked, but I cannot see any options for the WiFi networks. If there is any way to connect to the internet in a different way, please let me know.
Also if there are any better tutorials on how to install Ubuntu and boot from an external SSD, please let me know. I believe that the one I am following is fairly comprehensive.
@eyoung100 https://i.sstatic.net/MYmrP.png In this image, it shows what is in my pool/main folder. It does not contain the p/patch or the f/fakeroot path, so I think that might be causing something unfavorable to happen. Sorry it took me so long to get back.
Here are the contents of the make.log file that you requested:
