[CWB] Help with installation of new corpora

[D. Yuan]

Dear  All,

I installed the CQPweb by following Peter Uhrig's tutorial here 
(http://peter-uhrig.de/cqpweb-on-windows-10-wsl/) on Ubuntu 19.04. 
Nothing fishy turns out and  I can access the administration page and 
the web interface via both the localhost and the public ip address.  
However, when I tried to install the pre-encoded Dickens corpus, at the 
last step, I got:

"""

ERROR: CQP backend startup failed; the reported CQP version [] could not 
be parsed.

"""

What I did:

1) copy the Dickens data directory to the specified cqpweb data/index 
directory;

2) copy the Dickens registry file to the specified cqpweb registry 
directory;

3)  Fill in  corpus NAME and full description and install with the 
settings above

AND I have checked that cqp is in the path.

Do you guys have any idea of what I am missing?  Any pointers will be 
appreciated.

Best regards,

David
