Hello!

I have server with Ubuntu 16.04 LTS and Roundcube 1.2-beta. I would like to upgrade it. Current version has files/directories like below (installation directory):
root@s1:/usr/share/roundcube# ls -l
total 48
drwxr-xr-x 2 501 admin 4096 Apr 13 07:49 bin
-rw-r--r-- 1 501 admin 3595 Apr 13 07:49 config.inc.php.sample

I have a problem with upgrade it. When I just run bin/installto.sh from downloaded version directory I have error that "config directory does not exists". Ok, so I did "mkdir config" (and I did this same for another directories which don't exist in my current roundcube installation like logs, temp, etc.).

After making new directories I run again installto.sh script. Few las line from output:
CHANGELOG
README.md
UPGRADING
LICENSE
INSTALL
done.
!! Old .htaccess file saved as .htaccess.orig !!

JavaScript dependencies installation skipped...
Running update script at target...
This instance of Roundcube is not yet configured!
Open http://url-to-roundcube/installer/ in your browser and follow the instuctions.
All done.

there is information "done." and "All done" and when I log into some account I see I have 1.3.6 version but I see that database is not upgraded.

I used these tutorials:
https://github.com/roundcube/roundcubemail/wiki/Upgrade

https://linode.com/docs/email/clients/install-roundcube-on-ubuntu/

Could you help me with this?

Pozdrawiam / Best Regards
