I have tried to fresh install synapse. Though I have old backup which I want to restore to bring back my old rooms and chat. But both fresh install and restore is failing because of the dependencies error.
I tried to install the dependencies manually but it is failing too.
apt-get install coturn build-essential python3-dev libffi-dev python3-pip python3-setuptools sqlite3 libssl-dev python3-venv libxml2-dev libxslt1-dev python3-lxml libjpeg-dev libpq-dev postgresql acl

Package libjpeg-dev is a virtual package provided by:
libjpeg62-turbo-dev 1:1.5.1-2 [Not candidate version]
Package python3-pip is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
N: Ignoring file 'debian-testing.list.back' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Package 'python3-pip' has no installation candidate
E: Package 'libjpeg-dev' has no installation candidate
I hate the package mess ups. Ant solutions?
