  1. Hii,
    After unoserver installation I have start unoserver, and it’s done but after convert file that raised error. I have given details below that how I have performed commands and which error raised :

    This is using in docker because my project has docker configuration.

    #python3 -m unoserver.converter –convert-to pdf my.docx my.pdf
    Traceback (most recent call last):
    File “/usr/lib/python3.8/site-packages/unoserver/”, line 2, in
    import uno
    ModuleNotFoundError: No module named ‘uno’

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
    File “/usr/bin/unoconvert”, line 5, in
    from unoserver.converter import main
    File “/usr/lib/python3.8/site-packages/unoserver/”, line 4, in
    raise ImportError(

    Please help me and solve this out, if solved it is big thing for me.
    Thank you
