mynode_usb_driver_check.py fails with Python error

[erebor]

Hi, all. Trying to get mynode (RaspPi 4) to come back up after it shutdown for reasons unknown a while back. Upgraded to the latest release tag:

admin@mynode:~ $ cat /usr/share/mynode/version
0.3.32

I think I have the right Python3 version:

admin@mynode:~ $ grep PYTHON_VERSION /usr/share/mynode/mynode_app_versions.sh
PYTHON_VERSION="3.8.9"
admin@mynode:~ $ python3 --version
Python 3.8.9

But /usr/bin/mynode_startup.sh can't finish because /usr/bin/mynode_usb_driver_check.py fails, like this:

admin@mynode:~ $ python3 /usr/bin/mynode_usb_driver_check.py
Traceback (most recent call last):
  File "/usr/bin/mynode_usb_driver_check.py", line 7, in <module>
    from systemd import journal
  File "/home/admin/.local/lib/python3.8/site-packages/systemd.py", line 3, in <module>
    from cysystemd import (
  File "/home/admin/.local/lib/python3.8/site-packages/cysystemd/async_reader.py", line 29, in <module>
    class AsyncJournalReader(Base):
  File "/home/admin/.local/lib/python3.8/site-packages/cysystemd/async_reader.py", line 147, in AsyncJournalReader
    async def on_append(self) -> AsyncIterator[JournalEntry]:
TypeError: 'ABCMeta' object is not subscriptable

I don't know where to go from here. Any suggestions?

Yes, there should be a fix in the next release. To temporarily resolve, try running this command:

pip3 install "cysystemd<2.0.0"
