After downloading "" ucsf-chimerax_1.9ubuntu24.04_amd64.deb "" from https://www.cgl.ucsf.edu/chimerax/download.html, executing `sudo apt install ~/Downloads/ucsf-chimerax_1.9ubuntu24.04_amd64.deb`, I got an error message: chimerax: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by /usr/lib/ucsf-chimerax/bin/../lib/libpython3.11.so.1.0) At this stage, the previously working ChimeraX 1.7 is not working anymore. I figure this Ubuntu 22.04.5 LTS is using GLIBC 2.35-0ubuntu3.9. I could not install another ChimeraX version because of the same error. I also could not `sudo dpkg --remove --force-all ucsf-chimerax` because of the same error. I had to do the following. mkdir ~/chimerax-scripts-backup cd /var/lib/dpkg/info/ sudo mv *chimerax* ~/chimerax-scripts-backup sudo dpkg --remove --force-all ucsf-chimerax sudo apt-get -f install sudo apt-get autoremove dpkg -l | grep ucsf-chimerax And then reinstall a lower Ubuntu version's ChimeraX via `sudo apt install ./ucsf-chimerax_1.9ubuntu22.04_amd64.deb`.
