Worked for me as well, however there were these warnings:
WARN: bench is installed in editable mode!
This is not the recommended mode of installation for production. Instead, install the package from PyPI with:
pip install frappe-benchEnabled for site1.local
Should I worry 
No, this is actually the new normal for ERPNext installs. Nothing to worry about.

Yep, works like a charm… thank you for the steps… however, i run into hurdles if I want to upgrade the version of ERPNext from say 13.4 to the latest 13.5… Bench update runs with the Pip warning, but when I login to the application, it is still on 13.4… Any tips? Pointers?
Did you use the “Reload” function to refresh the frappe-erpnext cache in the browser?
Click on your icon in the upper right corner of the screen and select “Reload” from the drop down list. After it resets, check the version number again.
BKM
Seems like I was doing it wrong. I had to cd to the frappe-bench folder before updating bench. Once I did it properly, it worked well… Thank you for responding
Happily running 13.6 now
Confirmed successfully installed latest v13.6 on my Debian VPS cloud server 1Vcpu, 2G.
Many thanks.
instead of adding more domain to site1.local, do you know how to change it to different domain?
Edit the site_config.json for the site1.local site to delete the reference to the URL you wish to drop and save the file. (Be careful to keep the correct syntax for the file intact)
Then:
bench setup nginx
sudo service nginx reload
That will drop the URL assignment from the site. However, if your DNS pointers are still pointed to the site it may not stop the site login screen from being displayed. You will still be responsible for going to your DNS provider and changing the pointers manually.
Then using the previous instructions for adding a doman (URL) will let you finish the process of changing the URL assigned to the site.
Hope this helps.

I’m trying to install on a debian 11 vm. I am getting this error:

Probably not a very good idea to attempt installs on Debian 11. It is not stable yet and the installation process has only just recently become stable using Debian 10.
If you wish to continue to play on the fringes of software stability, please open a separate thread for those conversations.
Your error messages give the perfect example of why we do not use developing operating system versions to try to run ERPNext. The example here is that the installer could not find the install package for one for the system prerequisites ( wkhtmltopdf ) and the install crashed.
Again, please follow the tutorials as presented in order to have success. If you chose to use alternate operating system versions then start your own thread to search out the solutions. Visitors to this thread are looking for success with the tutorial and not failures of experimental OS versions.
BKM
I was not aware that ERPNext was not stable on Debian 11. Thanks for your help on this. I will try this on 10.
Brandon
This tutorial has worked for me, straight and concise, thanks and really appreciate it.
By the way, now I am in a dilemma to change the domain to a different one.
How would you go about it considering I have done the letsencrypt SSL configuration too.
Hopefully, soon I will be able to fully understand the whole architecture of the erpnext.
Thanks you in advance.
Ok… so all you have to do is a few simple steps:
bench setup add-domain --site site1.local [your.new.URL]
(This step actually adds an additional URL to operate with your site_config.json)
bench setup nginx
(This step forces the system to read the newly added info from the site_config.json)
sudo service restart nginx
(This step forces the nginx service to restart using new URL info in site_config.json)
This method of naming and renaming is much simpler than trying to rectify things if you had changed the directory names. I prefer using the method listed above.
Hope this helps.

AWS Lightsail with Debian 10.8
I followed the instructions precisely as specified, and created a user with name frappe.
When I invoke
sudo python3 install.py --verbose --production --user frappe --mariadb-version 10.5 --frappe-branch version-13 --erpnext-branch version-13
and after the mysql and Administrator passwords, I get the following error

I see this is not a new error as others have posted similar topics but without any resolution as yet. Does anyone have the faintest idea of how to resolve this.
