kopano-webapp-filesbackend-smb php7

Does the kopano-webapp-filesbackend-smb not work with php7

I allways get internal server error on uploading files to smb filesbackend - with nexlcout/owncloud backend everything works


Could your provide some information about your system.
Such as OS, webapp, files + backends versions etc.


It was Univention UCS 4.2-3
Upgraded to UCS 4.3
installed standard app form app-center - no repos for UCS 4.3
kopano-core uses debian9 repo = 8.5.5
webapp was befor upgrade 3.4.9 now (no repo for UCS4.3)
z-push was 2.4.0 after upgrade 2.3.8 (no repo for UCS4.3)
files was latest version now
file-smb-backend is now


@externa1 Is php-smbclient installed and activated?
And any output in the error.log?

php-smbclient was not installed after installing it seems to work now


If you use the debian9 repo for files there should be a dependency on:
php-libsmbclient which should provide php-smbclient

Btw, please upgrade to the latest files, it contains some important fixes:

no - i hope that repos for webapp, z-push for ucs 4.3 will be available soon from kopano


@externa1 Seems that I have the same problem. I have the same error-messages in log-file. I set up a new Univention 4.3 Server with Kopano Core from the kopano-repos. I hope for the repos soon too.

Ucs 4.3 and Debian 9 are nearly identical, so if everything you are waiting for are repositories, you can use the Debian 9 ones instead
