ls: unrecognized/unknown option «--color [»

Often there are predefined aliases. [...]

By predefined you mean predefine "by user" or "by the system"? I could use ls command before without any issues whatsoever and I haven't created any aliases for it.

In my opinion they are defined by the maintainers of a distribution. But by the way: There is an older thread on this topic in the web: superuser.com/questions/1145543/unable-to-use-ls-command-in-linux
They also suppose, it might be a wrong alias definition.

Hi [member=6215]JohnD[/member]
Thank you so much! The solution from the superuser forum worked like a charm Now I'm able to run ls just like I used to before. 
I simply had to run

Code:

unalias ls

and that did the trick.
