Example: https://packages.debian.org/sid/python3-kivy
- > > dep: python3 <https://packages.debian.org/sid/python3> (<< 3.7) dep: > python3 <https://packages.debian.org/sid/python3> (>= 3.5~) The ">=" surely means "greater than or equal to", but what is "<<"? "less than or less than"? Even more interesting is that "aptitude install python3-kivy" only shows one "<" (which makes sense to me as "less than"): The following packages have unmet dependencies: > python3-kivy : Depends: python3 (< 3.7) but 3.7.2-1 is installed > and in the description of the package in the aptitude console: Depends: python3-gst-1.0, python3 (< 3.7), python3 (>= 3.5~), ... > It's not a typo, unless other pages have similar typos (sometimes being ">>" - "greater than or greater than"?). Also, is the answer documented somewhere? I've researched unproductively for several hours. Thanks! -- Kent West <")))>< Westing Peacefully - http://kentwest.blogspot.com
