Linux raspberrypi 4.19.97-v7+ #1294 SMP Thu Jan 30 13:15:58 GMT 2020 armv7l GNU/Linux
installed v4.3.2
ubgraded to beta5, using instructions from announcements
NO problems encountered, pihole is running as expected.
Found 1 error in the syslog, I've never seen before:
Feb 16 10:27:39 raspberrypi systemd[2220]: gpgconf: running /usr/bin/gpg-agent failed (exitcode=2): General error
Feb 16 10:27:39 raspberrypi systemd[2220]: gpgconf: fatal error (exit status 1)
but apart from that (need to lookin to the error) everything appears to normal.
edit
cannot find a solution for the error, posted on raspberrypi.org forum here.
