On a relatively freshly installed Linux Mint 18.3, I've discovered that there is no
/etc/apt/sources.list file. This seems to cause no problems, but occasionally a warning pops up:
WARNING:root:could not open file '/etc/apt/sources.list'
(for example if I try to execute a command that does not exist in the command line).
AFAIU, on Linux Mint the standard sources are in
Will everything work as exepcted without
sources.list? Is it normal to not have it? If not, any ideas how it could get removed? (The warning was accidentally noticed about a week or two after the system was installed.)
Is it better to ignore the warning or to create an empty
/etc/apt/sources.list, or are there better solutions?
I understand that I can just create an empty file and the warning will probably go away, but I want to understand how this happened on a newly installed Linux Mint 18.3, and if it could be a symptom of some problem (maybe there are more important files missing somewhere).
