Anything else that would be useful to know?

install thrue yunohost think its installed thrue python

homeserver

It sounds like you're self hosting and your homeserver has no-one else joined to this room. If so, this is #1211.

[rosbeef]

i thougth that it was that, but i joined rooms with more peoples (800+) like #mobian:matrix.org (Room version: 9)
i i would like to join #freenode_#yunohost:matrix.org (150+ users) or #yunohost-dev:matrix.org (don't know the room version)

[bahur142]

This is not helpful, but. If your database is SQLite3, how is even possible to make federation? I thought PostgreSQL is a prerequisite to federate.

[DMRobertson]

Federation is possible when using both SQLite and Postgres. (Postgres is required to use multiple workers, however.)

[rosbeef]

sorry reading more carfully the installation files database is postgresql :

[squahtx]

From your logs, it looks like there was previously a half successful join to #yunohost:matrix.org that left the database in a bad state.
You can try the delete room API to clear the room off your server and rejoin: https://matrix-org.github.io/synapse/v1.73/admin_api/rooms.html#version-2-new-version

If possible, it'd be appreciated if you could find the logs containing the very first join to #yunohost:matrix.org (!GevpWevrsZKluNMXsY:pijean.ovh) to allow us to figure out what went wrong.

[rosbeef]

@squahtx peoples on yunohost told me that #freenode_#yunohost:matrix.org doesn t exist anymore but apear in the public room search list and the new one "#yunohost:matrix.org" doesnot apear.

so i tried the command you toldme :
$curl 'https://matrx.3cmr.fr:8448/_synapse/admin/v2/rooms/!GevpWevrsZKluNMXsY:pijean.ovh' -X 'DELETE' --header "Authorization: Bearer xxxxxxx" --data-raw '{"purge": true}'
${"delete_id":"XXXXXXXXXXXXXXXXXXX"}

Then i tried to joined and same error appear.

How can i send you a password in private to open the homeserver.loghomeserver.log
(just to say,it should be good to think about anonymizing logs)

[squahtx]

As noted in https://matrix-org.github.io/synapse/v1.73/admin_api/rooms.html#version-2-new-version, deletions run in the background. It is necessary to wait for the deletion to complete by checking /delete_status. Until then, the room should not be joined.

You can send the password to @squah:matrix.org

[rosbeef]

{"results":[{"delete_id":"puqKNGmWXkaaJIVg","status":"complete","shutdown_room":{"kicked_users":[],"failed_to_kick_users":[],"local_aliases":[],"new_room_id":null}}]}
and joining keepfailling

[DMRobertson]

and joining keepfailling

Please provide logs from a join attempt that failed after the deletion was completed.

[H-Shay]

I am going to close this for now due to lack of activity, we can re-open if it's still an issue and logs are provided - otherwise we have no way of diagnosing what's happening.

[rosbeef]

@H-Shay problem persist. logs are here https://paste.3cmr.fr/lufi/r/qB87AECMT0#9EPJ9DyplzNAhroVqRxKlsU6p9TfCEZda558aV+ZUNE= but if you can help me please share me a way to share you the password to access it. It seems @squahtx had no time to see my log.

[H-Shay]

I've re-opened as I was provided logs.

[rosbeef]

problem corrected, and don't know how, thanks for your time.
