When an HP printer stops working after a kernel upgrade or a stray RPM, the culprit is often an outdated HPLIP package from Fedora’s default repos, and this guide walks you through replacing it with the newest driver straight from HP’s own repository. First, enable the official HPLIP repo and clean your metadata before installing (or upgrading) the `hplip` package, making sure any old manual installs are removed so two versions don’t clash. After installation, check that the `hpcups` module is loaded, run `hp-setup` to register the device with CUPS, and watch for common pitfalls such as legacy firmware or kernel‑module mismatches that can silently break printing jobs. Finally, print a test page with `hp-test-setup`; if it displays correctly, your printer is back in business—if not, revisit the module load status and CUPS logs to pinpoint the issue.
This guide walks readers through installing the chkrootkit security utility on Ubuntu 22.04 and 20.04, beginning with a package‑list refresh before pulling the stable build from the official repositories. After confirming the binary’s location and permissions, users run an initial scan that also updates the signature database, then learn how to keep those signatures current with a simple command or by setting up nightly cron jobs that log results for later review. The article highlights common pitfalls—such as missing PATH entries or false positives—and offers quick fixes while stressing that a single scan can uncover hidden processes that otherwise slip past routine checks. Finally, it shares a real‑world anecdote where chkrootkit identified a data‑stealing rootkit, underscoring the tool’s practical value for anyone who suspects their system is acting strangely.
The guide walks you through fixing missing zlib.h and gzopen errors on Ubuntu 22.04 or 20.04 by first checking if the runtime library is already installed. If it isn’t, you run apt update and install zlib1g, then pull in libz-dev so your compiler can find headers and link correctly. The author includes a quick example where an OpenSSL build that stalled on “no such file” turns into a successful compile after installing the dev package, and shows how to test with gcc -lz. For those who need older versions or containerized libraries, there are tips about downloading specific packages or using Snap, though most developers will stick with the simple APT method.

This guide walks you through installing the most recent Nginx Mainline build on Rocky Linux 8 and 9, so you can take advantage of TLS‑v1.3 support and HTTP/2 improvements that older EPEL packages miss. It begins by removing any pre‑existing nginx or httpd binaries, then adds the official Nginx repository, enables the powertools stream on EL8, installs the package, verifies the mainline version with `nginx -v`, and finally starts and tests the service with a quick browser check or an OpenSSL command. Before you dive in, make sure you have sudo access, a clean Rocky installation, and that services like Apache are stopped to avoid port conflicts; also keep an eye on SELinux logs if network errors pop up. Once everything is working, your server will run the latest Nginx release with all its performance tweaks and modern security features.
