how to update roundcube to latest version, or i install roundcube latest version in ubuntu 18.04 ?

Hello
how to update ISP roundcube to latest version, or i install roundcube latest version in ISP ubuntu 18.04 ?

I can't find a suitable guide for the purpose
I've tried various combinations but I can't
fails to work roundcube.

Thank you in advance

 

Hello

i had originally installed with apt since ubuntu 16.04 , and it worked

update from ubuntu 16.04 to ubuntu 18.04 and been updated this worked too, but i noticed it was still an old version

I updated using the procedure installto.sh /var/lib/roundcube/

But from there everything started not working.

I solved it by editing the file manually and adding the password (
Error: SQLSTATE[HY000] [1045] Access denied for user 'roundcube'@'localhost' (using password: NO) in /usr/share/$
$share/roundcube/program/lib/Roundcube/rcube_db.php on line 201 (GET /roundcube/) )

the errors continued,
I was able to log in but then I didn't get any e-mails
I didn't even see the options when I went to setting.

He couldn't even log out anymore
PHP Error: Request security check failed (GET /roundcube/?_task=logout)

I wonder and believe that the solution is how to install the most recent version from scratch, an LTS roundcube 1.5 or 1.6.1 ?
the database has been updated for roundcube 1.6.1

I notice that it is very difficult to update roundcube 1.6.1 for ISP

now i have everything deleted even with apt purge roundcube
but even trying again I can't find the right way to install roundcube 1.6.1 or 1.5.1

Thanks in advance for any help in finding my way.

even worse now i cant even restart roundcube version with apt install i have these errors:
