I tried to install the full version of the adminder port but it fails with the following message: Unknown extension mssql for PHP 70.
As I see in PHP7 there aren't mssql module. I'll check it today or tomorrow. Thanks for your report!
Created attachment 180703 [details] patch Remove the options, download only one file. The php*-{mysqli,mssql,odbc,pgsql,pdo-sqlite} packages are only suggestion: the adminer.php loads only the selected extension.
I think the #222977 makes obsolote this report.
Seem solved with Bug #222977. No feedback from reporter. So I close here.
