feedparser error

[JoshuaFern]

Recently started having a problem running ytcc on NixOS Unstable, here's the error:

nixos-workstation% ytcc

During handling of the above exception, another exception occurred:

This error seems to come and go, I posted this issue 2 hours ago and it's now working again. I've done no reboots or updates.

I've also had this happen once before, I encountered this error and it disappeared awhile later.

I am getting the same error.

It seems that YouTube has rolled out an update, that sometimes breaks RSS feeds of some channels. I tried checking a feed manually and it indeed returned a feed without <updated> or <published> elements sometimes.

I'll implement a workaround that uses the current system time, if a feed entry does not have a <published> nor <updated> element

Fixed in v1.8.5
