I just use the ubuntu repositories for installation, no own builds.

deb bionic main restricted universe
deb bionic-security main restricted
universe multiverse
deb bionic-updates main restricted
universe multiverse

Version on Ubuntu: LibreOffice 00m0(Build:3)

Same problem on Debian Stretch server:

apt install openjdk-8-jre  openjdk-8-jre-headless
apt install libreoffice --no-install-recommends --no-install-suggests
apt install libreoffice-l10n-de

 # soffice --version
LibreOffice 20m0(Build:2)

deb stretch main contrib non-free
deb stretch/updates main contrib non-free
deb stretch-updates main contrib non-free
deb stretch-backports main contrib non-free

I am new to the libreoffice world.

I think, it is not a new bug but a mistake in waiting for request
(--accept mode), so we get an endless loop.

Where to set SAL_USE_VCLPLUGIN ?

Perhaps is that the way, I have to go?

Can I use the standard libreoffice on my notebook and parallel use the
new version with own compiling?
