I tried updating my Pi with the latest beta using the built in beta update process I have done many times.
The Pi refused to come back online after.
I got it connected to my LAN and ssh into the pi
I manually restarted by going to the ~/printer directory and "su ./printer"
It actually came back up and I could get in via web browser so I thought I was good.
I tried to do the update again and again it just died...relaunching from the command line would also not work I got a library missing error.
I then went in and moved the "printer" directory to a new name "printer.org"
then figured what the heck and did a command line reinstall.
(wget https://www.nanodlp.com/nanodlp.tar.gz --no-check-certificate -O - | tar -C /home/pi -xz --warning=no-timestamp);cd /home/pi/printer;sudo ./setup.sh
This worked but of course my system was all lost...I assume I might be able to copy back all the config from my printer.org directory
but before I did that I tried to do the beta update again...same problem it seems to just lock up...
when I went into the command line and tried to restart the printer process I get what I think is the same library error:
pi@raspberrypi:~/printer $ sudo ./printer
./printer: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory
pi@raspberrypi:~/printer $
Any thoughts on getting this working again...hate to loose all my setups etc.

sudo apt-get install libpng-dev
If not works try one below:
sudo apt-get install libpng16-16
Very confusing issue as raspbian changed the way libpng library works

no go.....
I even went back and reflashed my older backup which had my original nanodlp install.
Booted up in the printer everything worked....
did the beta update...back to dead
followed your instructions...see below....
pi@raspberrypi:~ $ cd printer
pi@raspberrypi:~/printer $ ls
build config distro install NOTICE public templates
change-distro.sh db expand-fs.sh LICENSE printer setup.sh upgrade.sh
pi@raspberrypi:~/printer $ sudo ./printer

Hmm looks like your OS need upgrade. Will try to lower libpng16 to 12
Offline
Lowered libpng requirement until old rasbian phased out. Try upgrade again.
Offline
is there a way to do the upgrade without the web interface being active?
similar to the full install using wget I assume?

Unfortunately no.

okay I will roll back to my backup and try the beta update using the lowered libpng again, but may try an os update first..

Tried an in place update from Jessie to Stretch.....it actually worked about as well as those things ever do.
Everything boots up but Nano doesn't launch complaining about something else....see below:
Note: this is with the previous beta that required the newer libpng
pi@raspberrypi:~ $ sudo lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description: Raspbian GNU/Linux 9.8 (stretch)
Release: 9.8
Codename: stretch
pi@raspberrypi:~ $ cd printer
pi@raspberrypi:~/printer $ ls
build config distro install NOTICE public templates
change-distro.sh db expand-fs.sh LICENSE printer setup.sh upgrade.sh
pi@raspberrypi:~/printer $ sudo ./printer
./printer: error while loading shared libraries: libGLESv2.so: cannot open shared object file: No such file or directory
pi@raspberrypi:~/printer $
I'll try going back to my backup with Jessie with working NanoDLP to try the beta update with the lowered libpng requirement.
Unless you want me to test anything here. I'll run a backup of this flash card as it stands before I roll back.

rpi-upgrade should sort out the issue.

I just got my system going again....back to Jessie running nanoDLP v2185...not sure if that is the beta or latest release....
Got my plates and db files moved over and while I have not yet started a print it looks to be good.
after I run some prints I may backup and try the rpi-upgrade...maybe also the stretch update.
Thanks

DrNK,
Download lite version not full fledged raspbian
Offline
Could not upgrade 2227 to 2229. Upgraded Raspbian a month ago to lite version successsfully.
Upgrade goes smoothly, PI3 goinf offline, manual restart, again still version 2227 exists. (tried install both stable and latest beta many times)
Offline
DrNK,
There were issue on build numbering, so 2227 the latest. It will be fixed with the next version.
