Description of my issue:

Hello,

After upgrading to Akeeba Backup 8 I got the "FOF40\Container\Container' not found" error on two out of 18 sites but, despite uploading the fof40 folder and resetting the Opcache the problem was not resolved. (Same as described here: https://www.akeeba.com/support/akeeba-backup-3x/Ticket/34649:class-fof40-container-container-not-found.html)

What did fix it for me was to delete the plugins/system/backuponupdate folder (which allowed me back into the site admin area) then reinstall Akeebabackup 8 twice. (I saw a similar ticket referring to the fof30 folder which led me to try this.)

The reasoning is the same as the other ticket you read. Joomla has a long standing issue where very realty it will not replace an old version of an extension with the new one — or at least some files. Installing twice in a row works. Of course if it's a system plugin that doesn't get updated properly while the rest of the extension is updated just fine you end up with a mix of versions that breaks your site. So yes, you do need to delete the plugin that Joomla failed to update to get back to your site to do the installation again.
