Hi All,
I managed to install ERPnext 13 on a Oracle arm64 server (that too in a LXC container) without much hassle. I will try to make a full guide in the coming weeks, but if someone wants to try now than please do this:
I followed the steps highlighted here: How to deploy ERPNext 13 on Ubuntu 20.04 LTS (Focal Fossa) | Scaleway Documentation and just changed amd64 to arm64 for the instructions to install wkhtmltopdf.
There was a few errors, but the markupsafe error was resolved by sudo pip uninstall MarkupSafe and then installing other version sudo pip install markupsafe==2.0.1 (source: Error while creating new-site - ERPNext - ERPNext Forum)
I haven’t checked the installation yet, but so far seems ok. Hope this helps.
