The Debian project has announced today the ninth point update of Debian 9 “stretch.” This update release mainly fixes security issues, along with few bug fixes.
Some obsolete packages were removed as well in this release, namely gcontactsync, google-tasks-sync, mozilla-gnome-kerying, tbdialout, and timeline.
The best part of Debian is how well it integrates its packages. Since all software is packaged by a coherent group, not only can all packages be found on a single site, but you can be assured that all the problems associated with complicated dependencies are already worked out by the dev team.
How to upgrade to Debian 9.9
Being a point update, you don’t have to do anything significant to upgrade to the new version. Run system update and you should be done with the upgrade.
Launch Terminal and enter the following commands.
sudo apt-get update
sudo apt-get upgrade
In the situation where the upgrade command is not getting the latest version, the dist-upgrade command can be used.
sudo apt-get dist-upgrade
After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror. A comprehensive list of mirrors is available at:
Debian 9.9 live ISO images are also available to download. The live images come in six different flavors including GNOME, Xfce, KDE Plasma, LXDE, MATE, and Cinnamon desktop environments.
Here are the download links of the complete image.
For other architectures, head-over to the official website.
Network boot users can set up a TFTP and DHCP (or BOOTP, or RARP) server to serve the installation media to machines on their local network. If your client machine supports BIOS, you can boot the Debian installation system from the network (using PXE and TFTP) and install the rest of Debian from the network. More details are available here.
Minimal ISO images are also available for download for various architectures.
