I am using Stable Debian (8.1 - jessie), installed from Live (debian-live-8.1.0-amd64-xfce-desktop.iso)...
Now, starting to install all other things, nothing is possible (!)...
apt-get and Synaptic not working...
apt-get install apache2: "E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)", "E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?".
with Synaptic interface: mark
apache2, ... When I press [apply] it says, at alert, "Could not apply changes, Fix broken packages first".
I am logged with
root in the descktop interface, and do (with no error alert) all the suggested updates,
apt-get update apt-get upgrade apt-get dist-upgrade apt-get install -f
