The guide explains how to troubleshoot the “Could not find CURL error” that shows up when curl cannot locate its libraries or is misconfigured. It walks through four steps—verifying installation, ensuring libcurl and related dependencies are present, checking PATH and linker cache, and validating SSL certificates—with commands for both Debian/Ubuntu and CentOS/RHEL systems. A real world anecdote demonstrates how a missing libssl caused a cron job to fail after an OS upgrade, and the fix involved installing the correct OpenSSL package from multiverse. Finally, it reminds readers to test curl again with a simple header request and offers reassurance that following these steps will eliminate the cryptic error.
If your site feels sluggish behind Nginx, start by checking whether gzip compression is already active with a simple curl request for the Content‑Encoding header. Once you confirm it’s missing, locate the correct configuration file—usually /etc/nginx/nginx.conf or the site‑specific block under sites-enabled—and add a gzip block inside the http context that turns the module on, sets vary and proxied any, chooses a balanced compression level of 6, defines buffers, and lists common MIME types. After saving, run nginx -t to catch syntax errors, reload the service without dropping connections, and then verify the header again with curl or your browser’s network tab to see the expected reduction in transfer size. In practice, missing the gzip_types line can cause a dramatic slowdown, so remember to include it and set gzip_vary if you’re using CDNs or need to support older browsers.
Fedora ships its own older Nginx package, which is fine for most sites but blocks newer features like HTTP/3 and upstream proxy directives. To get the bleeding‑edge mainline build, you add nginx.org’s Fedora‑specific repository by writing a repo file that points at the “mainline” directory and then run `dnf install nginx`. After confirming the version with `nginx -v`, you can rely on normal `dnf upgrade` commands to keep the server up‑to‑date, because the added repo feeds new releases directly. Finally, restart systemd’s nginx service and test a simple request to ensure everything is running correctly.

The article tackles the problem of installing QElectroTech on fresh Ubuntu systems and explains how dependency issues can appear after upgrades. It offers four main approaches: installing via the official Ubuntu repositories, using Flatpak from Flathub, grabbing a Snap package, or downloading and installing a .deb file directly. The guide also lists common pitfalls such as missing Qt libraries or icon theme problems, and provides quick fixes like installing libqt5widgets5 or adwaita‑icon‑theme. By choosing the method that best fits your preference for simplicity, isolation, or automatic updates, you can start drawing schematics without further hassle.

The guide explains how to get Microsoft Teams working on Rocky Linux 8 or 9 by sidestepping the Windows‑only myth with a clear, step‑by‑step process.
It begins by ensuring root access, an internet connection, and EPEL are enabled, then pulls in core development tools and essential libraries before downloading Microsoft’s official RPM from their repository mirror.
After installing the package with dnf—which automatically resolves dependencies such as libXss and libsecret—users may need to import Microsoft’s GPG key and address any missing libraries that surface when launching Teams.
The article also covers common issues like black screens, audio loss, or license expirations, offering quick fixes so users can keep collaborating smoothly on Rocky Linux.
This guide walks you through installing the latest MySQL 8.0 on Rocky Linux 9 or 8 in less than ten minutes, bypassing the older packages that ship in the default repos. It starts by checking for and removing any MariaDB installations that could block MySQL’s port, then adds the official MySQL Community Edition repo from dev.mysql.com tailored to either EL 9 or EL 8. After pulling down the community server package—which brings InnoDB, SSL libraries, and optional replication tools—the instructions turn on firewall rules for TCP 3306 and enable SELinux networking so remote clients can connect without error. Finally it starts and enables the mysqld service, runs the secure‑installation script to harden root access, and suggests a few handy tweaks like changing the character set or enabling slow‑query logging before you begin using your new database.
