Unable to finish setup.
I am using a Raspberry PI 4B
Power is supplied via the header
I have the USB-C port wired into the USB port of the ChituBoard
Serial connection has been verified RX to TX, TX to RX, and GND to GND
RaspiOS was installed via Raspberry Pi Imager using the Raspberry Pi OS Lite (32-Bit)
I have followed many guides, including this one, and the auto installer.
if mention(this one)="https://l9o.dev/tags/mariner3d/"
if mention(auto installer)="https://github.com/KTheMan/Mariner-Autoinstaller"
I have also followed the guide trying to update/create a symbolic link from Python 3.7 to Python 3.9
if mention(python)="https://github.com/luizribeiro/mariner/issues/481#issuecomment-968325624"
However, I receive this error.
if mention(error)= "pi@resin:/opt/venvs/mariner3d/bin $ sudo ln -s python3.7 /usr/bin/python3.9 ln: failed to create symbolic link '/usr/bin/python3.9': File exists"
No matter, I still have ended up with no web GUI and the status showing as below.

PS: I'm just joking around with coding portions. Nor am I trying to be exact with it.
Looks like the root issue is Python, so there's a couple things you can try. I would try to completely remove and reinstall Python and its symlinks. It may also work to just reinstall the OS from a fresh download and hope that the symlink issue isn't baked into the RPiOS release.
For the former option, this is where I'd start: https://askubuntu.com/a/1202976
EDIT: Looks like the same issue as #481, so check there first
same problem, try fix it with python3.9 but i receive this error:

Problem solved,
I installed python 3.7.4 but it was very long as a process on RPi Zero W, about 4 hours to compile it complete with optimization; without optimization about ~1 hours; I highly recommend compiling it with optimization.
Use root account, build and install python then install mariner (uninstall if installed):
apt-get update -y
apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev libgdbm-dev libnss3-dev libreadline-dev -y
cd /usr/src
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz
tar xf Python-3.7.4.tar.xz
cd Python-3.7.4
./configure --enable-optimizations
make -j $(grep -c processor /proc/cpuinfo)
make altinstall

ln -s /usr/local/lib/python3.7/ /usr/lib/python3.7
Optionally: Delete the source code and uninstall the previously installed packages
cd /usr/src
rm -r Python-3.7.4

I also ran into this issue, looks like nothing has changed. I'm looking forward to trying Mariner out -- is @antwal's fix the preferred path?
Following antwal's process had the same end result; I can confirm it definitely takes an afternoon to execute it and I still don't have a working mariner build. The error after following the process is the same as I got before. I stated at that point and uninstalled Mariner, followed the process, and then reinstalled mariner. Thanks if anyone's looking at this!

Hi, since I published the fix a lot of changes have been made to the mariner code and most likely it doesn't work correctly anymore, to help the whole community you can publish the errors you receive and the process you used and on which distribution and version? Thank you.
I'm going through the process again tonight and will document and post tomorrow. Right now it's on test 131/416 and it's been doing the tests for 3 hours. 8-)
Ok, well I've made some progress. I'm going to keep taking a look at it and may open another issue. Going through again after formatting the SD card seems to have helped. Here's the steps I followed:
- Hardware: new Sandisk 32GB micro SD Card, Raspberry Pi Zero W
- Format Fat32, default allocation size
- Write Raspberry Pi OS Lite 32b(20220404) to SD card with Raspberry Pi Imager v1.7.2, enable SSH, set up wifi, hostname, and pw
- Eject disk and install in Pi
- Wait until green light is consistently on
- SSH into pi at
.local with pi user -
sudo -s - Execute 'antwal procedure' above
- Follow Mariner installation procedure from documentation
- Reboot
- Confirm Mariner is running with
sudo systemctl status mariner3d - Connect to pi via web browser at [http:](http://
:5000/)
These results are encouraging and far better than my prior attempts. I attribute this to starting over from scratch rather than trying to bandaid something that wasn't working.
Mariner loads into web browser, however I'm not fully working yet. Currently getting the following (wondering what that "elegoo_mars.get_selected_file" is all about. I'm using an Anycubic Photon Mono 4k.

just to be sure, have you configured the serial port correctly?
however I have not updated the operating system to the latest version because the one I used was working correctly, if I have time in the next week I download the version you used and try to see if it works
@Rhastlyn I made a new installation and it works perfectly, the error you receive is almost certainly a serial port configuration problem or you have connected the cables wrong and there is no correct communication with the printer, check the installation and configuration procedure and definitely solve the problem.
This won't be a viable solution for everyone, but after lots of headache around trying to compile and install python 3.7, I just reflashed my SD card to a fresh version of Raspberry Pi OS based on Debian Buster (the latest of which was released in 2021 and can be found here). On that version, the install "just works"-ish. Additional hoops I had to jump through to get the GPG key are documented here.
This comes with some security risks since that release is not likely receiving security patches anymore, and we're using an expired gpg key. I decided to take these risks since it works and I'll not be connected to the internet.
