[Solved] Failed to run Electrum-4.2.2 on Linux Lite 6.0

[jack0m]

Hi, I installed Electrum-4.2.2 on Linux Lite 6.0, but when I try to launch the app, it won't start and the console shows the following errors:

Code:

[...]
  File "/home/jack/.local/lib/python3.10/site-packages/electrum/paymentrequest_pb2.py", line 36, in <module>
    _descriptor.FieldDescriptor(
  File "/home/jack/.local/lib/python3.10/site-packages/google/protobuf/descriptor.py", line 560, in __new__
    _message.Message._CheckCalledFromGeneratedFile()
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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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 your 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).

Am I missing any library?

It's likely because of #52b7388.

Try to solve it as the workaround suggest. You can downgrade the library using:

Code:

pip install protobuf==3.20.1

Ok, that worked out. Many thanks!

pip install protobuf==3.20.1

Since this is a runtime error, you should probably create a virtualenv before/after doing this so that subsequent installs of completely unrelated packages don't alter the protobuf version that you installed manually. It can happen e.g. if you install a lot of python-based programs e.g. youtube-dl or you have a Python environment such as Anaconda.

Something like this, since you're installing & running Electrum from the command-line:

Code:

python3 -m venv electrum
source electrum/bin/activate
<install electrum & protobuf, and run electrum here>
deactivate # To get out of the virtualenv - just `deactivate` works.

Ok thanks, I'll give it a try.
