Some month ago, i installed Quickbox and used the Btsync services without any problem.
Two days ago, i have noticed that btsync was disabled and i could not enable it.
I have tried to reinstall it using the quickbox dashboard but i've got the same result so i tried to reinstall it via ssh.
Here is error message i've got
user:/home/user# box install btsync
sudo: unable to resolve host user
The user does exist so i don't understand the error message.
I am running Debian 8 on my server.
Thank you for your help
