Trying to install
letsencrypt on Debian Jessie, I have run into the following situation I don't quite understand. I already have installed
dpkg -l | grep acme ii python-acme 0.6.0-1~bpo8+1 all ACME protocol library for Python 2
Now I'm trying to install
apt-get install python-letsencrypt Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: python-letsencrypt : Depends: python-acme (>= 0.5.0) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
What is the meaning of this error message? As far as I can tell, I have the right version of the package installed (
>= 0.5.0, right?) Why does the package manager refuse to see it?
