[opencms-dev] module import fails in 6.0.4

[Uhlig, Roman]

Hi,

I'm trying to copy a module from an OpenCms 6.0.4 installation to
another one of the same version. After exporting the module, copying it
to the target machine and importing it via "Import module from server",
I get the following error message:

Error uploading the module xyz.zip.
Cannot import module from source
"/var/lib/tomcat5/webapps/opencms/WEB-INF/packages/modules/xyz.zip". It
is already installed.


The module has never been installed before on this machine, neither
shows it up after the failed import attempt.

Is there any (other) way to get this working?

Thank you in advance,
Roman Uhlig
