Fix 'invalid or corrupted package (PGP signature)” error in Arch Linux

I have a few ArchLinux systems installed in both physical and virtual machines that I access when needed. Nearly two months later, when I tried to upgrade ArchLinux in one of them using sudopacman-Syu, I encountered hundreds of errors like this: Invalid or Corrupt Package Error in ArchLinux Example The problem is when you encounter the above error , you cannot upgrade/update your Arch system. Even if you synchronize mirrors or get faster mirrors. So, if you run sudopacman -Syyu, the error still exists. This creates difficulties because you cannot install any other packages until this problem is fixed. Reasons when you install or upgrade on ArchLinux system

finally! Ubuntu launches 'immutable'!

finally! Ubuntu launches 'immutable'!

Which Linux concept is popular this year? "Immutability" is definitely indispensable. Ubuntu finally couldn't hold it any longer. Just in early June, Canonical, the parent company of Ubuntu, announced that it would soon join the immutable distribution trend. While Snap's lead developer Oliver Grawert casually dropped the announcement in a post on the OMGUbuntu website at first, Ubuntu desktop product manager Oliver Smith "picked it up" in a blog post the next day and confirmed it again: It will be coming next year. The next long-term support version (LTS) released in April, in addition to the traditional version based on the deb format, will also launch a new version built entirely based on the Snap format. The latter is

Sometimes you just need to dig into the terminal. For a well-rounded developer, basic command line knowledge is essential. You should be familiar with the command line, be able to edit files, configure applications - all the basics.

Not to follow Windows 11, Linux will not only continue to support AMD Zen 2, but also optimize its performance

According to news on June 3, according to foreign technology media NeoWin, the Linux distribution will not follow Win11. It will not only continue to provide support for AMD Ryzen processors based on Zen2, but also further improve performance by optimizing the L3 cache (LLC). The operating system will assign tasks to processor threads marked as "idle", but the current Linux kernel can only identify idle threads in the local L3 cache; the select_idle_sibling() patch recently released considers calling an external LLC. IT Home attaches two pictures here, showing the structural diagram of AMDZen2CCX and CCD. You can see the difference in cache structure between single CCD and dual CCD: single CCD

It allocates clients from the DHCP pool or the IP address range specified in its configuration. While you can manually assign static IPs to client systems, a DHCP server simplifies the process and dynamically assigns IP addresses to client systems on the network. In this article, we will demonstrate how to install and configure a DHCP server on RHEL9/RockyLinux9. Prerequisite: Pre-installed RHEL9 or RockyLinux9 with sudo management permissions
