im not making sense of this

thank you very much for your continued support!

i am not sure which file you are referring to. this is tree from /etc/apt:

root@anytype:/etc/apt# tree
.
|-- apt.conf.d
|   |-- 01autoremove
|   |-- 20listchanges
|   `-- 70debconf
|-- auth.conf.d

    |-- debian-archive-trixie-automatic.asc
    |-- debian-archive-trixie-security-automatic.asc
    `-- debian-archive-trixie-stable.asc

its been clear for awhile now that the script is doing pretty much nothing: because, as you can see: even the keyrings directory is empty, so its not even able the repo, hence it cant find docker-ce. im not sure where it fails. if downloading the asc file, dearmoring, adding repo…

as you can see im running as root by the way, so no need to become.

how do you suggest i debug this? sorry for my total lack of knowledge.

docker_pre_apks:

• apt-transport-https
• ca-certificates
• curl
• gnupg2
• libssl-dev
• python3-cffi-backend
• python3-pip

docker_apks:

still same result :(

i have NO idea what i am doing wrong. this is new to me. but i personally learn better with practical examples rather than reading books and documentation. i thought setting up docker was simple enough to begin… i guess i was wrong.

i dont see how, i have been doing this: https://www.manelrodero.com/blog/docker-en-proxmox-lxc-con-turnkey-core on maaany lxcs and they all work just fine!

thanks for sharing! and this works for you? as i said on my original post (on selfhosted channel), im new at ansible and i must be doing something stupid.

this is your yaml very slightly adapted:

this is my inventory file:

my workflow is not completely broken because i managed to get this workbook working:

  hosts: all
  gather_facts: yes

  tasks:

  - name: Copy custom CA certificate
    copy:

its of course a lot simpler…

it was a brand new host. the first (this above) playbook worked, but then the docker one didnt. so it doesnt seem to be a target host issue. both debian 13 lxc if that matters.

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?

oh! I wasnt aware of that? i see its slightly outdated, it has version 26 as opposed to 29 from its official source. at least in trixie stable

WOW. I HAVE NOT THOUGHT OF THAT!!!111

How about a friendica instance? Like nerdica.net
