Google webmaster gives crawl errors for non-existent URLs, why?

Question

Web development

Actually, in the webmaster, it gives scanning errors.
I open
And there
There are no such categories, urls, on the site, especially this last one "amsamoa/1/lukovaya-dieta.html" is not at all clear where it came from?
The urls have nothing to do with the site.
In robots, everything is fine.
What could be the problem

Answer 1

Most likely, such materials were once upon a time (see the date), if they are not there now, just remove them and that's it.
If you're worried about broken links, run your site through Xenu , it will show you where your broken links are and how the program found them.

Answer 2

look at the sitemap, is there anything strange?

Answer 3

Probably your domain is not the first freshness. Apparently the index remained from the previous owner. It will pass with time.
