In this tutorial : The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1 5 Update your Debian Installation It recommanded to add : contrib non-free for : Code: deb http://deb.debian.org/debian/ buster main contrib non-free deb-src http://deb.debian.org/debian/ buster main contrib non-free deb http://security.debian.org/debian-security buster/updates main contrib non-free deb-src http://security.debian.org/debian-security buster/updates main contrib non-free But I have more lignes, I have : Code: deb http://deb.debian.org/debian buster-updates main deb-src http://deb.debian.org/debian buster-updates main deb http://deb.debian.org/debian buster-backports main deb-src http://deb.debian.org/debian buster-backports main Your tutorial are very clear, then maybe I know the answer already , if you didn't talked about these additional lignes, we should'nt add contrib non-free because we are no going to get stable version ! Right ? So we just need to add contrib non-free only for the lignes mentioned in your tutorial ? right ?
Backports are not used in the tutorial, so the packages from there have not been tested against ISPConfig. Backports might work nonetheless, but it can also be that backports contain versions that are not supported by ISPConfig yet, then your system will fail. The tutorial uses the sources.list configuration that ships with the official Debian 10 install media, your sources.list seems to be extended by the hoster where you rented your VPS. If you want to use backports to test if the new versions are compatible, then you should add contrib and non-free there as well.
It is always a risk to change the version of some software, especially when using ISPConfig or similar additional layer above the OS since ISPConfig assumes software is the intended version and configured in the usual way. If you break these assumptions it is necessary to test if it still works. So it would be foolish to add backports repo and update everything from there. But there is a better way, using apt pinning only a certain package is installed from backports, the others stay at the stock version. So if there is a valid reason to upgrade to the version in backports it can be done once it is tested to work.
I agree, thank for your advices The best way is to check in ISPConfig -> Tools -> Updates, then like this we are sure to stay in accordance with ISPConfig That the right way about the update ? or we can still use : apt-get update apt-get upgrade
Why is that best way? Does your ISPConfig Panel have that item? Operating system update is best done following the documentation of OS.
I don't know, I beleive IspConfig can be magic and will let me know important update in : ISPConfig -> System -> Updates -> Apps Addons It's just for a new version of ISPConfig ?
This is not related to system updates in any way. This is an installer for ISPConfig addons, but there are no addons available yet.
