Every "must-have Linux tools" list recommends the same tools and none of them tell you what apt actually installs. Ubuntu 24.04 ships fzf thirty releases behind upstream, a Flameshot that predates its own Wayland fix, and a Node.js that has been end-of-life since April 2025 — while the docker.io advice everyone still repeats is now wrong. Every version here was read from a real 24.04.4 system and compared against upstream on the same day.
CopyQ is not broken — it is the most capable clipboard manager on Linux and 16.0.0 shipped on 30 May 2026. People leave it over the dated Qt interface, the scripting they never use, or Wayland behaviour that is usually their distro shipping a three-year-old build. Here is what each alternative actually is, how it reads your clipboard, what it is licensed under, and when CopyQ is still the right answer.
On Wayland, which clipboard manager works is decided by your compositor, because the data-control protocols are not universally implemented. This is the per-compositor answer for GNOME, KDE Plasma, Hyprland, Sway and the rest, checked against the protocol registry, the compositor source trees and the distro package indexes in August 2026. It also covers the version traps that break the usual advice: wl-clipboard on KDE, Pano's upstream status, and how far behind Ubuntu's GPaste actually is.
Clipmer's headline feature is masking secrets before a screen share. An audit found the fastest way past it was the menu item directly above the button that turns it on — plus a GNOME hotkey signed to a dead PID, a D-Bus check that authenticated nothing, and a three-line fix that was worse than the bug it closed.
Wayland deliberately forbids the one thing a clipboard manager needs to do. Here is the security model behind that, the two data-control protocols that work around it, which compositors implement which (GNOME implements neither), and how each Linux clipboard manager actually reads your clipboard.
Ubuntu ships no clipboard history. Four options that work on both Ubuntu 24.04 and 26.04 LTS — Clipboard History, GPaste, CopyQ, and Clipmer — with install commands checked on each release, what happened to Pano, and what to do when an extension stops loading after the upgrade.
