More context: When I try Jay’s solution, I receive the following errors:
E: Malformed entry 58 in list file /etc/apt/sources.list (URI parse)
E: The list of sources could not be read.
Curiously, this error repeats 3 times. (Perhaps because I’ve tried to do this too many times and have installed multiple flawed versions of the same thing? If so, I’ve no idea how to clean that up…)
