Roundcubemail: Upgrading from 1.2.0 to 1.2.3 doesn't work

[lug-gh]

Hi,
I have roundcube 1.2.0 installed, i'm not really sure in which directory.

I have /opt/www/roundcubemail/ and /opt/www/roundcubemail-1.2.0/
so I updated both with bin/installto.sh, this is the console output:

./installto.sh /opt/www/roundcubemail-1.2.0/
Upgrading from 1.2.0. Do you want to continue? (y/N)
y

Copying files to target location...done.

But when I repeat this step, it still shows "Upgrading from 1.2.0", so I guess the update failed?
In the Roundcube Panel its also listed as 1.2.0 (even after reboot)

Additional Information:

Ubuntu 16.04.1
PHP 7.0.8

I'm using roundcubemail with iredmail

Looks like error handling could be better. Do you have rsync installed?

[lug-gh]

Yes, I have.
Shall I just copy a fresh installation of roundcube 1.2.3?
Will my configs stay?

[alecpl]

Yes. 1.2.0 -> 1.2.x is pretty safe update.

[lug-gh]

Ok it worked, ty :)

[alecpl]

Done.

@lug-gh @alecpl I'm experiencing the same. What have you done to make it work?

The iRedMail-developer ZhangHuangbin gave me a hint how to solve this issue. In PHP the system function has been disabled. I've enabled it and the update worked as expected.

@scroom as written above, i copied a fresh installation of the newest roundcube folder and replaced the old version with that files, then restarted the server.

And which system function are you talking about? Could be useful for others to know.

@lug-gh I've meant the php function "system" in the php.ini. In my case it has been marked in the php.ini as disabled function. I've deleted it from the list and the update worked as expected:

After the update you should re-disable the system function.
