Perhaps upping the requirement here would fix this https://github.com/newslynx/newslynx-core/blob/master/requirements.txt#L59

I'm not sure what is also requiring that library, though, and causing the error.

[mhkeller]

@abelsonlive do you foresee any problem using 0.1.8 instead of 0.1.7. Changelog: http://pyasn1.sourceforge.net/changes.html

[mhkeller]

Note. This error also occurs when running automation into virtualbox. It could be that one of the dependencies has changed its dependency.

[mhkeller]

Hmm this fails even after updating opportunities to include the 0.1.8 requirement. it throws the same error citing 0.1.7 being asked for

[abelsonlive]

try just removing that requirement?

[mhkeller]

that was the error output after removing pyasn from newslynx-core requirements

[abelsonlive]

Just tested on Virtualbox + AWS and ran fine: https://github.com/newslynx/newslynx-core/commit/ada9cb01d66e4e04ef7f71d9447c35ab9bbbb28d
