I've tried following instructions from other links related to this, but it is still not working.

I also understand that this issue might not be related to duplicity, however if someone could guide me in the right direction it would be really helpful. I've searched StackOverflow, but to no avail.


System: Debian 10
Librsync version 0.9.7-10+b1

Let's say I'm currently in /home/ashish/projects


Steps to reproduce:
1. Install duplicity

sudo apt update
sudo apt install librsync-dev

wget https://code.launchpad.net/duplicity/0.8-series/0.8.04/+download/duplicity-0.8.04.tar.gz
tar xf duplicity-0.8.04.tar.gz

cd duplicity-0.8.04

python3.7 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt
pip install pydrive

./compilec.py

deactivate


2. Run duplicity with pydrive as backend

PYTHONPATH=".:.venv/lib/python3.7/site-packages" ./bin/duplicity . gdocs://username@xxxxxxxxx/backups/duplicity


ERROR:

Traceback (most recent call last):

ImportError: librsync.so.1: cannot open shared object file: No such file or directory


$ ldd duplicity/_librsync.cpython-37m-x86_64-linux-gnu.so

        linux-vdso.so.1 (0x00007ffd18366000)
        librsync.so.1 => /usr/lib/x86_64-linux-gnu/librsync.so.1 (0x00007f8a0f9c3000)
        libpython3.7m.so.1.0 => not found
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f8a0f7a6000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f8a0fdd5000)


I can clearly see that librsync.so.1 is present in cache using,

$ sudo ldconfig -v | grep librsync

ldconfig: Path `/usr/local/lib' given more than once
ldconfig: Path `/lib/x86_64-linux-gnu' given more than once
ldconfig: Path `/usr/lib/x86_64-linux-gnu' given more than once
ldconfig: /lib/x86_64-linux-gnu/ld-2.24.so is the dynamic linker, ignoring

        librsync.so.1 -> librsync.so.1.0.2


$ ls -la /usr/lib/x86_64-linux-gnu/librsync*
