I removed gnuradio (3.9), changed the PPA to point to
gnuradio-release-3.8, updated, and installed.
Gnuradio got replaced with 3.8.2. However all flowgraphs are
still broken, initial problems areh the number of parameters being wrong
on lots of blocks. For example:
Traceback (most recent call last):
File "/home/tom/Desktop/top_block.py", line 285, in <module>
main()
File "/home/tom/Desktop/top_block.py", line 261, in main
tb = top_block_cls()
File "/home/tom/Desktop/top_block.py", line 131, in __init__
self._RxF0_win = RangeWidget(self._RxF0_range, self.set_RxF0, 'RxF0', "counter_slider", float, QtCore.Qt.Horizontal)
TypeError: __init__() takes from 5 to 6 positional arguments but 7 were given
