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

Do you want to setup Lemmy for development, or to run a production instance? We have docs for both, so please try to follow those, and explain where exactly you are getting those problems.

The mdbook error means that it couldnt find the documentation, but Lemmy works fine without that.

Hi thanks for your reply i tried again with ansible now i get this error when try to start my ansible.cfg makes reference to python3 however :

sudo ansible-playbook lemmy.yml --become
/usr/lib/python2.7/dist-packages/ansible/parsing/vault/init.py:44: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecate d in cryptography, and will be removed in the next release.
from cryptography.exceptions import InvalidSignature
ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/lemmy/ansible/lemmy.yml': line 104, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  • name: start docker-compose
    ^ here

I think that you are missing the dependencies for Ansible's docker_compose command.
