Older Toolbox containers failing to run on Fedora Linux 35 or CentOS Stream 9

Problem

Trying to start toolbox on Fedora Linux 35 (or another newer Linux distribution) would result in an error like:

Error: invalid entry point PID of container fedora-toolbox-34

Cause

The newer build was using library symbols unavailable in older versions. See
#529: /usr/bin/toolbox linked against glibc-2.32 doesn’t run on older glibc for the technical details.

Solution

An update has been released to fix this issue.

After you update your system in your usual way (and possibly reboot), you should no longer be affected by it.
