Output of running umbrello5 from the terminal in openSUSE

SUMMARY
Umbrello exports empty DocBook and XHTML files.  The console output indicates that Umbrello is looking for the required XSLT files in a directory that does not exist.


STEPS TO REPRODUCE
1. Install Umbrello from the operating system's software repositories.
2. Open Umbrello and create a UML diagram.
3. Export the model via File >> Export model >> Export model to XHTML.
4. Select the directory for the output.


OBSERVED RESULT
The action fails with the message "XHTML Generation failed ."  The diagram is generated successfully as a PNG file in the output directory, but the DocBook and XHTML output files are empty.


EXPECTED RESULT
The DocBook and XHTML files are generated, and contain the UML model's documentation.


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed 20200201
KDE Plasma Version: 5.17.5
KDE Frameworks Version: 5.66.0
Qt Version: 5.14.1

ADDITIONAL INFORMATION
The problem also exists on Manjaro Linux with the same KDE and Qt software versions noted above.

Exporting the DocBook output does not generate an error, but the output file is still empty.

When run from the terminal, Umbrello indicates that it is searching for an XSLT file in a directory that does not exist.  The path varies between the two aforementioned operating systems, but in both cases the path name suggests that Umbrello is searching for the absolute path of the XSLT file on the system that built the installer package.  On openSUSE Tumbleweed, the path is "/home/abuild/rpmbuild/BUILD/umbrello-19.12.1/umbrello/docgenerators/docbook2xhtml.xsl".  I have attached the output from running Umbrello on openSUSE.

A possible workaround is to create a symbolic link from the directory named in Umbrello's command-line output to the directory where the XSLT files are actually installed.
Comment 1 Ralf Habacker 2020-02-16 05:32:54 UTC 
There are two issues: 

> umbrello: XSLT is' "" '

This indicates that umbrello cannot find the required xsl stylesheet, which is provided on the openuse system by the docbook-xsl-stylesheets package and does not appear to be installed. 

For https://build.opensuse.org/package/view_file/KDE:Applications/umbrello/umbrello.spec?expand=1 this runtime dependency is missing.

> umbrello: Local xsl is' "" '
This indicates that umbrello5 search the file docbook2xhtml.xsl in the wrong directory, which is a bug inside umbrello https://github.com/KDE/umbrello/blob/d426a5dbcfe1a6a20a50b8b25c07887f4889537c/umbrello/docgenerators/xhtmlgenerator.cpp#L261.

Use the global xml catalog to replace external docbook.xsl uri

It does not work with Mingw builds of libxml2 2.9.8 and is now obsolete
with the support of the global xml catalog.
