I am trying to install a new discourse instance on a new root server with Ubuntu 22.04
Our “old” server crashed today with major hardware failure so our hosting provider had to setup a new server. (I do have the discourse backup file from last night that I wanted then to reload into the newly setup instance.)
I am following these steps:
But the installation fails with the following error:
x86_64 arch detected.

But already the start of discourse-setup does show several errors.
Looks like the script is not working correctly with the German version of the Ubuntu operating system.
The errors are the lines with $avail_mem and that is because the memory cannot be determined.
Your script is looking for Mem: but in the German Ubuntu it is Speicher: when free -m --si is executed.
Same with Swap: which is Auslager: in the German version.
I have not seen any hint, that the OS has to be the English version in order to install Discourse.

So I modified discourse-setup and replaced Mem: with Speicher:and Swap: with Auslager: and then discourse-setup did run fine without errors:
