I’m encountering a unique issue where I’m unable to connect to the Snap Store using snapd on an AWS Lightsail instance. This instance is IPv6-only and is running Ubuntu 22.04 LTS. My attempts to install or update snaps are being hindered by this connectivity issue, despite having confirmed IPv6 internet access.
Environment Details:
Cloud Provider: AWS Lightsail
Instance Configuration: IPv6-only
Operating System: Ubuntu 22.04 LTS
snapd version details: 2.61.3+22.04
Troubleshooting Steps Taken:
- Internet Connectivity Check: Confirmed the instance’s access to the internet using IPv6 ping commands to well-known external sites.
- Firewall Rules Verification: Ensured the instance’s firewall permits outbound traffic on essential ports (22 for SSH, 80 for HTTP, and 443 for HTTPS) for all IPv6 addresses.
- DNS Resolution: Successfully performed a DNS lookup for the Snap Store’s domain using an IPv6 DNS server, confirming proper resolution.
- Direct Connectivity Test: Managed to directly ping the Snap Store’s IPv6 addresses, verifying reachability.
snapdConnection Attempts: Despite the successful tests above,snapdfails to connect to the Snap Store, with logs indicating a timeout error.
Additional Attempts:
Executed standard commands to refresh snapd and clear potential proxy configurations, without success.
Observations:
This challenge presents itself on a freshly set up IPv6-only Lightsail instance, which lacks any custom network configurations like proxies or VPNs. The issue doesn’t arise in environments that support both IPv4 and IPv6, hinting at a possible IPv6-specific complication.
Questions:
Has anyone experienced similar issues with snapd over IPv6, especially in cloud environments like AWS Lightsail?
Are there particular configurations or steps for snapd on IPv6-only setups that I might have overlooked?
I would greatly appreciate any suggestions for further troubleshooting or resolution steps.
Thank you in advance for any insights or assistance you can provide.
