Installation runs into "Failed to get release information" (fresh Hetzner Ubuntu 22.04 Server)
-
Hi everyone,
I started a fresh Ubuntu 22.04 VPS at Hetzner Cloud:
Welcome to Ubuntu 22.04 LTS (GNU/Linux 5.15.0-41-generic x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage System information as of Fri Jul 15 03:59:53 PM UTC 2022 System load: 0.0 Processes: 146 Usage of /: 5.6% of 37.23GB Users logged in: 0 Memory usage: 9% Swap usage: 0% 0 updates can be applied immediately.but when I try to install Cloudron the setup runs into an error while checking for release informations:
############################################## Cloudron Setup (latest) ############################################## Follow setup logs in a second terminal with: $ tail -f /var/log/cloudron-setup.log Join us at https://forum.cloudron.io for any questions. => Updating apt and installing script dependencies => Checking version Failed to get release informationI have already checked various hints from other posts, but none led to the solution. Do you maybe have any ideas?
I hope anyone can help.

@kk_cloudron Can you please try this on the server?
curl "https://api.cloudron.io/api/v1/releases?boxVersion=" -
@girish This runs into
# curl "https://api.cloudron.io/api/v1/releases?boxVersion=" curl: (7) Couldn't connect to serverThere is no error output with other targets.

@kk_cloudron take a look if the Firewall at Hetzner Robot is turned on. If so, turn it off ^^
-
@subven Hehe, nice try
My steps after reading your post:
- Firewall was opened at 80 and 443. - not working
- Disabled Hetzner firewall - still not working
- Checking iptables:
# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination- Checking ufw:

Do u use IPv6? If so can you try to disable the IPv6 interface and just use IPv4? Hetzner has IPv6 only plans for their Cloud VPS but it should not fail due to ipv6. Since you have Firewall, Network or DNS issues there is no harm in trying.
Your output for
ping -v api.cloudron.iois odd...you should at least be able to resolve to 3.209.21.239.Do you get a positive result when ping or curl api.cloudron.io?

@kk_cloudron said in Installation runs into "Failed to get release information" (fresh Hetzner Ubuntu 22.04 Server):

The ping is not supposed to work. The curl should just return a 404 since there is nothing at the root path.
$ curl https://api.cloudron.io <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>Error</title> </head> <body> <pre>Cannot GET /</pre> </body> </html> -
@subven I only use IPv6. So turning it off will be difficult
@girish All right. Thank you for the info. is there another way to pinpoint the cause of the problem?
I read somewhere that there may be problems with the images offered by Hetzner. Is it still relevant? Should I try installing a different image or is there a list of the required packages so I can compare?
-
"solved" - but I don't know for sure the exact reason that caused this. I set up a new server with both: IPv4 and IPv6.
So best explanation/guess: the installation only works if there is also an IPv4 -
K kk_cloudron has marked this topic as solved on
-
@kk_cloudron that is correct, Cloudron requires IPv4 and does not work on IPv6 only servers (yet).
