No module named notifications.common

[J. Max Mena]

As the title suggests, trunk r18103 breaks servers - making them fail to start with the following traceback:

Traceback (most recent call last):

For reference I'm using a Fedora 26 machine for my server and starting it with xpra start :13 --bind-tcp=0.0.0.0: --start-via=proxy=no --systemd-run=no --start-child=xterm

• I very much doubt that it is r18103 that causes this problem (renamed the ticket), please explain how you came to this conclusion
• r18110 introduced xpra.notifications.common

r18117 should fix the RPM packaging for it, moving it to python2-xpra and python3-xpra which is common to both clients and servers

[J. Max Mena]

My bad I read the wrong column on https://xpra.org/trac/changeset/18110/xpra#file13.....which is from r18110. And, rolling my server back to r18102 had it working again since it was before that change.

[J. Max Mena]

I upped my server to r18117 and it's still failing to start servers with the same error - I'm building from source not using a package

[Antoine Martin]

I'm building from source not using a package

Using what command line?

Try r18118 or later.

[J. Max Mena]

r18118 fixes it for me.

For reference here is the build command I've been using for a while now:

#clean up build info
rm -f xpra/build_info.py
rm -f xpra/src_info.py

#clean up old build
./setup.py clean

#LDFLAGS=-Wl,-rpath=/usr/lib64/xpra \
#PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib64/xpra/pkgconfig \
#    ./setup.py install
#no longer needed
python3 ./setup.py install \
--rpath=/usr/lib64/xpra --pkg-config-path=/usr/lib64/xpra/pkgconfig \
--without-html5 --without-printing
rm -f /usr/bin/xpra
python2 ./setup.py install \
--rpath=/usr/lib64/xpra --pkg-config-path=/usr/lib64/xpra/pkgconfig
