[tor-relays] [tor-assistants] Running obfs4proxy on Debian Stable

Hash: SHA256

If you want to try to install jessi without updating your system it's
possible. Add repositry to /etc/apt/sources.list, run apt-get update.
Then use this and only this command to upgrade only that package from
new repository (check if you need to replace jessie with unstable or
something like that):

apt-get -t jessie install name of your package

You don't need to remove repository from your sources list because
this command will lock upgrades of other packages. Check this url for
more info: https://wiki.debian.org/AptPreferences, in section
"Installing from unstable".
