Drupal 8.x

How can I adapt this theme to use a sticky footer? Apart from that, if I don't use a footer, how can one make this theme have pages take up 100% of the browser page height when the content is smaller? I have some css overrides, but I am so far unable to work out what to set. Have tried height = 100% on body and #main-container and other things I think are wrappers, to no avail.

I've the Solr search API and when I try to enable it I get this error "Solr search requires the solarium/solarium library."  

I've installed the solarium/solarium library via Composer and I am still getting this issue. I've spent a week trying to figure this out so any help is greatly appreciated. 

I have a Windows 10 setup with Composer, and Drush.

When I try to install anything using Drush (ex $drush dl webprofiler --debug) I get "unable to decompress" error as shown in the image below.  (Image did not load so here is the text from CMD)

I am relatively new to developing with Drupal, and I hoped to get some information on the best way to approach a simple problem.

In efforts to add support for entity labels containing parentheses, I would like to alter the method call extractEntityIdFromAutocompleteInput($input) in the \Drupal\Core\Entity\Element\EntityAutocomplete class.  

It seems some others have been having problems updating core to 8.7, I tried following the steps in

But I still get an error running # drush updb
