I have no idea what "info about AdminTools" you are talking about. The error message does not reference Admin Tools. Moreover, Admin Tools has stopped shipping a Joomla! Update feature since 2012, that's five years ago. The error you are getting comes from Joomla's own database update (SQL) files. The Joomla! leadership is responsible for maintaining these files. We are not affiliated with it or endorsed by it.
I would strongly recommend going to Extensions, Manage, click on Database and then click on the Fix button. This should detect any database errors and try to fix them for you. Again, please note that this issue is completely unrelated to Admin Tools. As such we can provide no further support for it. Sorry.
