• [*] Did you retain the logfile (path of logfile is shared while the script is run)? We definitely need the logfile to debug any easy install related issues.
• [*] Is this something you can debug and fix? Send a pull request! Bug fixes and documentation fixes are welcome

Possible Solution

[ViktorNova]

Mine failed in this same exact way.
Also on Ubuntu 20.04, running in an LXC container

Looking at the install logs, it appears that it has failed because of trying to write to /proc/sys/vm/swappiness, which is impossible on a container

EDIT: Turns out frappe/bench#811 solved my problem!

[idolaru]

Could someone help how to fix this issue ? Unfortunately I don't really understand how to apply the solution from frappe/bench#811
