Hi list,

Ive found the reason for failing lvmdbusd: The install-script installs
the python-module-dir "lvmdbusd" into /usr/lib/python3.6/site-packages.
Unfortunatly this path is not in the standard-python(3)-modulepath included:

--------------- snip -------------------------

ver@w541:~/gits/lvm2$ python3 -m site
sys.path = [
    '/home/oliver/gits/lvm2',
    '/usr/lib/python36.zip',
    '/usr/lib/python3.6',
    '/usr/lib/python3.6/lib-dynload',
    '/usr/local/lib/python3.6/dist-packages',
    '/usr/lib/python3/dist-packages',
    '/usr/lib/python3.6/dist-packages',
]
USER_BASE: '/home/oliver/.local' (exists)
USER_SITE: '/home/oliver/.local/lib/python3.6/site-packages' (doesn't exist)
ENABLE_USER_SITE: True

--------------- snap -------------------------

It seems the "site-packages" dir is in Ubuntu a local one in the current
home dir. Putting the moduledir "lvmdbusd" into
/usr/lib/python3.6/dist-packages works fine. For me it is sufficient to
change the installation-path to this dir.

I don't know, how the paths are organized in other distros like fedora
or redhat, but maybe you find a way installing the lvm2-python3-parts
for lvmdbusd in a way which works also out of the box for ubuntu, too.

Tfh!

Oliver
