ld-elf.so.1: /bin/sh: Undefined symbol "__libc_start1@FBSD_1.7"

Have problems updating to 14.0-RELEASE, i have read the notes and all,
also about problems when upgrading.

ran
# freebsd-update -r upgrade 14.0-RELEASE
from a 13.2 system
had some problems with /etc/master.passwd, and /etc/group
there were some
<<<<<<<<<<<
current version
=====
stuff I had to delete.
Shell was not changed.  ran freebsd-update install after reboot
process hung and did not do anything.  I tried
# freebsd-update rollback
and I get this error.  I am checking how to update from source, but I
would need to fix the system somewhat, short of reinstalling how to I
troubleshoot this?
Any advice ? build from source no git found pkg install git does not work.
Any ideas as to how to proceed short of a reinstall?

Internet as working but when I restarted after reboot to install first
updates, internet did not start automagically :(
I had to run some commands even though it was working in 13.2 but not here.
# ifconfig wlan0 up scan
# ifconfig wlan0 ssid NAMEOFWIRELESSPROVIDER here
# killall -9 dhclient
# dhclient wlan0
and successfully connected.
when running to upgrade pkgs I get
root@coolermaster:~ # pkg-static upgrade -f

Thank you in advance

P.S.  One machine successfully running FreeBSD 14 after upgrades, ran
testing versions BETA through RC4 and ran freebsd-update to
14.0-RELEASE and updated all packages.
