External Email - Use Caution

I’m assuming you tried to install the freesurfer 7.4.1 release deb package for Ubuntu 22 which is available via the link,https://secure-web.cisco.com/1-8cAL3HeYSqkGt1gxwntnID8i3xh2XIP7o3oNj46aWRvzM... libc message seems to indicate your version of Debian Linux uses a newer version of the system glibc compared to what was used to build freesurfer on Ubuntu 22 linux.  If you run this command on your Debian linux system,

$ ldd --version

… and it reports a version of 2.36 or higher, then you would need to revert to an older release of Debian linux that uses glibc 2.35 in order to install the freesurfer Ubuntu 22 7.4.1 package.  While Ubuntu Linux is a derivative of Debian Linux, the OS names/versions do not strictly overlap, i.e., the version of Debian Linux needs to match or be compatible with Ubuntu 22 Linux for the install to work.   The chart below shows Debian bookworm spans both Ubuntu 22 and Ubuntu 23 linux; you are likely running the newer bookworm version matching Ubuntu 23 which changed glibc to a version > 2.35 - R.
