I just opened up a flowgrah that used to work, where I send messages into
virtual sources and sinks to get around the fllowgraph. Now, when I open
the flowgraph, I get these messages in console and the wires connecting the
messages to the virtual sources are deleted.
>>> Error: Connection between digital_probe_mpsk_snr_est_c_0_0(noise) and
virtual_sink_1(in) could not be made.
sink key "in" not in sink block keys
Traceback (most recent call last):
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/grc/base/FlowGraph.py",
line 415, in import_data
raise LookupError('sink key "%s" not in sink block keys' % sink_key)
LookupError: sink key "in" not in sink block keys
I updated to GNU Radio 3.7.9rc1 about a month ago but didn't notice this
issue until now. I'm also using Ubuntu 14.04.
