Fatal error after EB3 upgrade

Hi

My EasyBlog 3.9.22295 has prompted to upgrade, saying there was a newer version. I went to the Updater, which told me version 3.9.24862 was available (I think I went through that procedure once already).
Using my staging server, I started the upgrade (I have the API key entered as required).
The update started:
- downloading patch files
- Upgrading Foundry framework

but stalled after that. After a while, I realized that the site was dead. attempt to load any page, either front or back end results in:

Warning: require_once(/var/www/xxxxx.com/s/public/media/foundry/3.1/joomla/framework.php): failed to open stream: No such file or directory in /var/www/xxxxx.com/s/public/components/com_easyblog/constants.php on line 228



Fatal error: require_once(): Failed opening required '/var/www/xxxxx.com/s/public/media/foundry/3.1/joomla/framework.php' (include_path='/var/www/xxxxx.com/s/public/plugins/system/shlib/shl_packages//ZendFramework-1.11.7-minimal/library:.:/usr/share/php:/usr/share/pear') in /var/www/xxxxx.com/s/public/components/com_easyblog/constants.php on line 228

I restored the site, tried again, with same result.

What should I do from there?
