Installing Electrum, "TypeError: Descriptors cannot not be created directly."

[mahesh]

Installed as per the instructions on Electrum.org. Or tried to, anyway. Did I do something wrong? (Ubuntu 20.04; Beginner)

    Code:

Code Select Expand

$ electrum

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate you protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
