If I run the downloaded installation script with the -u option to upgrade my existing installation, it fails as shown below. If I move my existing anaconda3 directory out of the way and install from scratch (i.e. run the script without -u) it completes successfully, but of course I no longer have my previously created Anaconda environments available.
(base) waugh@UNKNOWN:~/Downloads$ bash ./Anaconda3-2025.06-0-Linux-x86_64.sh -u
