I am running the current Debian 9.6 Stable (stretch). My
sources.list is as follows:
I think this
sources.list came with the original clean install.
I do routine updates weekly. Occasionally, several weeks have gone by with no updates, but I would say that is unusual.
The commands I run for the update are as follows:
Code:
cat /var/log/unattended-upgrades/unattended-upgrades.log
sudo aptitude update
sudo aptitude safe-upgrade
My
aptitude commands are equivalent to your
apt-get commands, as far as I know. My first command with
cat is to see if any unattended upgrades have been installed, but Testing may be exempt from unattended upgrades (not sure).
