Every time I try to use any of the tools that post web page content I’m getting error: "AttributeError: 'HTMLParser' object has no attribute 'unescape'"
So far we see this happens with: Blog Post, Help Article, Web Page, and TODO. This prevents being able to post any of these items, and indeed being able to finish setting up the site.
We are new to ERPNext, we’re trying to migrate away from Odoo and Plone, and hoping that ERPNext might be a good solution, it looks promising in the online demos/trials, now if we could just get it fully working on our own servers. 
This is a fresh install of ERPNext on Debian 11 (we are required to use this IS version, we may not downgrade to Ubuntu or older versions of Debian lower than 11).

Appreciate any suggestions on how to resolve this, it is a show stopper.
Thanks!
