How To fix connection to api.snapcraft.io in Ubuntu upgrade

Ubuntu 20

In this article, we will discuss how to fix connection issues to api.snapcraft.io during an Ubuntu upgrade. This is a common issue that many Ubuntu users face while upgrading their systems. The problem can occur due to various reasons, including proxy settings, snapd service issues, or temporary downtime of the snap store.

Quick Answer

To fix connection issues to api.snapcraft.io during an Ubuntu upgrade, you can try clearing proxy settings, restarting the snapd service, or using an external HTTP proxy. If none of these solutions work, you can check the status of api.snapcraft.io on status.snapcraft.io to ensure it’s not a temporary issue.

Clearing Proxies

One of the most common reasons for this issue is incorrectly configured or problematic proxy settings. If you have proxy settings configured, clearing them might resolve the problem.

You can use the following commands to clear the proxy settings:

sudo snap set system proxy.http=""
sudo snap set system proxy.https=""

In these commands, sudo allows you to run commands with administrative privileges, snap set system is used to modify system-wide configuration options, and proxy.http and proxy.https are the HTTP and HTTPS proxy settings, respectively.

Please note that if you’re using a proxy, make sure to include the full URL containing http in the proxy address.

Restarting snapd

The snapd service is a background service that manages and maintains your snaps. Sometimes, restarting the snapd service can help establish a connection to api.snapcraft.io.

You can restart the snapd service using the following commands:

snap refresh snapd
systemctl restart snapd

In the first command, snap refresh snapd, refresh is used to update the snap packages and snapd is the package we’re targeting. The second command, systemctl restart snapd, uses systemctl to control the systemd system and service manager, and restart is used to restart a service, in this case, snapd.

If you encounter the error snap snapd is not installed, first install snapd using apt with the command sudo apt install snapd and then execute the above commands.

Using an External HTTP Proxy

If the above solutions don’t work, you can try using an external HTTP proxy with snapd. This is a more advanced solution and is typically used in a corporate environment where all internet traffic is routed through a corporate proxy.

You can refer to this Ask Ubuntu post for instructions on configuring an external HTTP proxy.

Checking the Status of api.snapcraft.io

If you’re experiencing the same error as mentioned in the linked post, where the snap store was temporarily down, the solutions provided above may not be applicable. In such cases, you can check the status of api.snapcraft.io on status.snapcraft.io to ensure it’s not a temporary issue.

Conclusion

In this article, we have discussed several ways to fix the connection issue to api.snapcraft.io during an Ubuntu upgrade. By clearing proxies, restarting snapd, or using an external HTTP proxy, you should be able to resolve this issue. If all else fails, it’s a good idea to check the status of the snap store to make sure it’s not temporarily down.

Remember, it’s important to understand what each command does before running it. If you’re unsure, you can always refer to the man pages or online documentation for each command.

We hope this article has been helpful in resolving your connection issues with api.snapcraft.io. Happy upgrading!
