@sshcli please double check that you updated from 3.6.5. The error looks like you updated from beta or other dev version.

Rename the alias column in the #__fields table to name and you're good. Closing as a known issue since maintenance team has elected to not support non-stable updates.

This is why i have asked to double check if he direct updated from 3.6.5 if yes than this is a valid issue.

I have tested with both:
Update from 3.6.5 and got the warning
Update from 3.7.0-rc1 and got the error

The "Alias" column doesn't exist in my installation. (Updated from 3.6.5 to 3.7.0-rc3)
I only have the column "name"

Maybe we are facing another bug, very similar but different

I can not confirm this kind of errors on my installation. I have just tryed 3.6.5 -> 3.7rc3-dev

I think you could reproduce the issue by making a clean installation of 3.6.5 and then unzip 3.7.0-rc4 in the root directory of your server.
