Install MariaDB
Installing the Frappe Framework
Getting production-ready

Problem 1 - Install MariaDB section

On Install MariaDB section, I ran into an issue regarding 404 Not Found Mirror Repository.

Error Output:

Ign:1 https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu focal/main arm64 mysql-common all 1:10.6.8+maria~focal
Ign:1 https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu focal/main arm64 mysql-common all 1:10.6.8+maria~focal
Err:1 https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu focal/main arm64 mysql-common all 1:10.6.8+maria~focal
  404  Not Found [IP: 197.155.77.1 443]
E: Failed to fetch https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu/pool/main/m/mariadb-10.6/mysql-common_10.6.8+maria~focal_all.deb  404  Not Found [IP: 197.155.77.1 443]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Temporary solution: I replaced https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu to https://mirrors.gigenet.com/mariadb/repo/10.6/ubuntu

Problem 2 - Installing the Frappe Framework Section

On Installing the Frappe Framework section, I ran into an issue regarding soft_unicode and markupsafe.

Error Output:

lance@erpnext-arm64v8:~$ bench init /home/lance/frappe-bench --frappe-path https://github.com/frappe/frappe --frappe-branch version-13 --python python3
Traceback (most recent call last):

    from markupsafe import Markup, escape, soft_unicode
ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/usr/local/lib/python3.8/dist-packages/markupsafe/__init__.py)

Temporary solution: I attempted to fix it by running this command: sudo pip3 install markupsafe==2.0.1. Luckily, it worked.

Problem 3 - Getting production-ready

On Getting production-ready section, when I run the command sudo bench setup production <name>, it ran into an issue regarding Jinja2.

Error output:

No solution was found on Problem 3 - Getting production-ready. I’m still stuck in this. Please help me. Thank you.

Comment: It seems the Ansible update June 22, 2022 broke the documentation.

Stuck on the same point… Ansible requires jinga 3.0 while bench requires 2.10.3 is there a fix for this conflict?

You need to setup supervisor and nginx manually.
.
Replace “sudo bench setup production ” with following commands (change amadeus to you non-root sudo username)

cd /home/amadeus/frappe-bench

pip install ansible==5.4.0 ansible-core==2.12.2 jinja2==2.10.3

sudo apt-get install supervisor nginx

bench setup supervisor
bench setup nginx

sudo ln -s /home/amadeus/frappe-bench/config/supervisor.conf /etc/supervisor/conf.d/frappe-bench.conf
sudo ln -s /home/amadeus/frappe-bench/config/nginx.conf /etc/nginx/conf.d/frappe-bench.conf

sudo shutdown -r now

Hope this help
I followed this tutorial.

A simple solution Just fork any frappe/erpnext release between 13.11.x - <13.25.x , run bench update --reset to force version change then you’d be good to go.

Thes problems will be sorted in no time and you’ll be able to move to that new version.
