Seven servers successfully updated to 3.2 using https://www.howtoforge.com/updating-ispconfig-3-1-to-ispconfig-3-2/. A big thanks to the team. Small note: The Intel Buster based servers upgraded perfectly. The apt-get command for Debian/Ubuntu revealed that rar was not in the Debian repository for ARM64 or the RPi-OS repository for ARMH. I presume the same may apply for all the ARM downstream repositories. The unavailability of rar and the minor consequence were noted under the Centos upgrade instructions. It may be worth adding a similar note to Debian/Ubuntu installation/update instructions.
