I have previously installed this successfully on a Raspberry Pi 3 which recently died. I have tried unsuccessfully to install on my new Pi 4 4GB a few times. I have updated, upgraded, did a dist-upgrade, and I get the same results. I even tried to put the SD card from the Pi 3 into the Pi 4 as I read that it should work, but no go.
Here is what I see upon the failure: If the version you run (./config.guess) is already up to date, please send the following data and any information you think might be pertinent to <config-patches@gnu.org> in order to provide the needed information to handle your system. config.guess timestamp = 2008-01-23 uname -m = aarch64 uname -r = 4.19.127v64 uname -s = Linux uname -v = #1 SMP PREEMPT Fri Jun 12 22:09:51 CEST 2020 /usr/bin/uname -p = /bin/uname -X = hostinfo = /bin/universe = /usr/bin/arch -k = /bin/arch = /usr/bin/oslevel = /usr/convex/getsysinfo = UNAME_MACHINE = aarch64 UNAME_RELEASE = 4.19.127v64 UNAME_SYSTEM = Linux UNAME_VERSION = #1 SMP PREEMPT Fri Jun 12 22:09:51 CEST 2020 configure: error: cannot guess build type; you must specify one Citadel Easy Install is aborting. The last few lines above this message may indicate what went wrong. Linux Debian 10.6( 4.19.127v64 aarch64) I hope this helps. Thanks, -Stan Anderton
