I previously used jmtpfs to mount an android phone connected
via usb. Now having issues mounting a recently acquired
nokia 6 with android pie.

First issue was missing /lib/udev/mtp-probe in dmesg output.
That was resolved by installing libmtp-runtime.

Now I get:

I upgraded from 4.9 kernel to 4.19 and continue to have this issue.

According to apt-cache search, udev is a transitional package for
eudev. So does that mean I have an issue with eudev?

Grateful for any advice toward diagnosing or resolving this
issue!
