Installing Arch Linux in VirtualBox

I've covered installing Arch Linux on a system, but installing it on VirtualBox is a bit more tricky. Technically, there is only one very important aspect of installing on it on VirtualBox that is different. I have tested this quite a bit for installations and cloning a machine also works well. Download To start, you need the ISO file for the installation. The website is at โ€˜https://archlinux.org/download/โ€™.

[$] Debian debates amending architecture support stratagem

The Linux kernel supports a large number of architectures. Not all of those are supported by Linux distributions, but Debian does support many of them, officially or unofficially. On October 26, Bastian Blank opened a discussion about the minimum version of these architectures that Debian should support: in particular, raising the de-facto minimum versions in the next Debian release ("forky"). Thread participants were generally in favor of keeping support for older architecture variants, but didn't reach a firm conclusion.

Postmortem of the Xubuntu.org download site compromise

In mid-October, the Xubuntu download site was compromised and had directed users to a malicious zip file instead of the Torrent file that users expected. Elizabeth K. Joseph has published a postmortem of the incident, along with plans to avoid such a breach in the future: To be perfectly clear: this only impacted our website, and the torrent links provided there. If you downloaded or opened a file named "Xubuntu-Safe-Download.zip" from the Xubuntu downloads page during this period, you should assume it was malicious. We strongly recommend scanning your computer with a trusted antivirus or anti-malware solution and deleting the file immediately. Nothing on cdimages.ubuntu.com or any of the other official Ubuntu repositories was impacted, and our mirrors remained safe as long as they were also mirroring from official resources. None of the build systems, packages, or other components of Xubuntu itself were impacted.
