uninitialized constant Jekyll::Filters::DateFilters
After a massive update on my personal computer, I was no more able to run the local instance of this blog. In particular, there was an error related to Jekyll, as shown below:% bundle exec jekyll serve
Traceback (most recent call last):

Did you mean? DateTime
I therefore decide to remove the packaged version of Jekyll (that was
3.1-something with regard to 3.9 currently available) and also Ruby, so to start over a very clean environment:
% apt remove jekyll
% apt remove ruby
% apt install ruby
% sudo gem install bundler
Then, of course, I installed all the dependencies for the static site content:
% bundle install
% bundle update
and finally I was able to serve this blog on my local machine again!
It happens to me more and more ofter: (K)Ubuntu is messing up my environment and is not able to handle updates in a proper way. I was using Kubuntu 20.04, and I have updated all my stuff quite regularly but in the last months I have been away from the keyboard, and this could have been produced an invalid all-in-one update.
Or maybe it could be the update done via
Discover.
Or I don’t know…
