I have tried install a instance of lemmy on ubuntu using cargo and i get a lot of errors :

[ERROR] (mdbook::utils): Error: Couldn’t open SUMMARY.md [ERROR] (mdbook::utils): Caused By: No such file or directory (os error 2)

then i tried with ansible but without success too:

error: system does not fully support snapd: cannot mount squashfs image using
“squashfs”: mount: /tmp/sanity-mountpoint-253231470: mount failed:

there is a good tutorial how to install an lemmy instance and point then to a self domain?

thanks in advanced
