jless v0.9.0 pre-built Linux binary (x86_64-unknown-linux-gnu) fails on Ubuntu 24.04 with: jless: error while loading shared libraries: libxcb-shape.so.0: cannot open shared object file: No such file or directory. The README only documents X11 libs as build-from-source dependencies, not runtime dependencies for the release binary.
Install the missing X11 clipboard library: sudo apt-get install libxcb-shape0. On Ubuntu 24.04, the other three xcb deps (libxcb1, libxcb-render0, libxcb-xfixes0) are already present — only libxcb-shape0 is missing. The full set from the README is: sudo apt-get install libxcb1 libxcb-render0 libxcb-shape0 libxcb-xfixes0.
