because in soviet russia, you dont delete a post. a post deletes you.

v29 is a big update https://www.reddit.com/r/docker/comments/1ounfw8/docker_29_api_changes_breaking_changes/ ive made lxc config changes, and id like to have everything on the same update lvl. no have some apps with a lxc config because of official repos, and some other ansible powered with a lower version. i like to have everything on the same update level so i dont go crazy updating my homelab. besides, this would be “dodging” the problem. in my ansible training, id like to be able to add a repo to a given server.

yeah thats the thing - its apparently not doing ****. no keyring, no repo but it is connecting to the remote server. it does say on the log anytype.lab; which is my target server, and its selected from the correct inventory file:

i know it must be something terribly stupid. but i just cant put my finger on it

could you maybe please send me the whole thing?

sweet! looking forward to it!

hum unfortunately either im doing something else wrong or its not working for me
