I have a Debian 8.11 server and I'd like to upgrade it to Debian 9 first and to Debian 10 afterwards.
I did the following:
apt-get update
apt-get upgrade
apt-get dist-upgrade
All finished with no errors and if I repeat the commands above they say that there are 0 packages to be upgraded. Thus I assume that it went well.
Nonetheless, my system is still 8.11:
$ cat /etc/debian_version
8.11
$ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
NAME="Debian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=debian
HOME_URL="http://www.debian.org/"
SUPPORT_URL="http://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
What can be the problem? I was trying to follow Upgrades from Debian 8 (jessie)
