Installing Snap Packages with Web Proxy

Ubuntu 5

In today’s article, we are going to discuss how to install Snap packages when you are behind a web proxy. This is a common scenario in many corporate environments where internet access is controlled via a proxy server.

Quick Answer

To install Snap packages with a web proxy, you have several options. You can specify the proxy server using Snap system options, configure the proxy environment variables for Snapd, create configuration files for the Snapd service, or edit the Snapd configuration file directly. Choose the method that works best for your specific setup and replace the <proxy_addr> and <proxy_port> with the actual values of your proxy server.

What is a Snap Package?

Snap is a software packaging and deployment system developed by Canonical for the operating systems that use the Linux kernel. The packages, called ‘snaps’ and the tool for using them ‘snapd’, work across a range of Linux distributions allowing distribution-agnostic application packaging.

Setting up the Proxy for Snap

To install Snap packages behind a web proxy, you have several options:

1. Specify the Proxy Server Using Snap System Options

You can specify the proxy server directly using Snap’s system options.

$ sudo snap set system proxy.http="http://<proxy_addr>:<proxy_port>"
$ sudo snap set system proxy.https="http://<proxy_addr>:<proxy_port>"

In the above commands, replace <proxy_addr> with the IP address or hostname of your proxy server, and <proxy_port> with the port number.

2. Configure the Proxy Environment Variables for Snapd

You can also configure the proxy environment variables directly for the Snap daemon.

First, edit the /etc/environment file and add the following lines:

http_proxy=http://<proxy_addr>:<proxy_port>
https_proxy=http://<proxy_addr>:<proxy_port>

Then, restart the Snap daemon for the changes to take effect:

$ sudo systemctl restart snapd

3. Create Configuration Files for Snapd Service

Another option is to create configuration files specifically for the Snap service.

First, create a folder for the Snap daemon and create configuration files for the environment variables:

$ sudo mkdir -p /etc/systemd/system/snapd.service.d/
$ echo -e '[Service]\nEnvironment="http_proxy=http://<proxy_addr>:<proxy_port>/"' \
 | sudo tee /etc/systemd/system/snapd.service.d/http-proxy.conf
$ echo -e '[Service]\nEnvironment="https_proxy=http://<proxy_addr>:<proxy_port>/"' \
 | sudo tee /etc/systemd/system/snapd.service.d/https-proxy.conf
$ sudo systemctl daemon-reload
$ sudo systemctl restart snapd

4. Edit the Snapd Configuration File

The final option is to edit the Snap daemon configuration file directly.

Open the Snapd configuration file in a text editor:

$ sudo vim /etc/sysconfig/snapd

And add the following lines:

http_proxy=http://<proxy_addr>:<proxy_port>
https_proxy=http://<proxy_addr>:<proxy_port>

Conclusion

In this article, we’ve covered several ways to install Snap packages behind a web proxy. Remember to replace <proxy_addr> and <proxy_port> with the actual values of your proxy server.

While these methods should work for most versions of Ubuntu and Snapd, it’s always a good idea to check the documentation for your specific version if you encounter any issues.

The article provides step-by-step instructions for each option.

How do I specify the proxy server using Snap’s system options?

To specify the proxy server using Snap’s system options, use the following commands:

$ sudo snap set system proxy.http="http://<proxy_addr>:<proxy_port>"
$ sudo snap set system proxy.https="http://<proxy_addr>:<proxy_port>"

Replace <proxy_addr> with the IP address or hostname of your proxy server, and <proxy_port> with the port number.

How can I configure the proxy environment variables for Snapd?

To configure the proxy environment variables for Snapd, edit the /etc/environment file and add the following lines:

http_proxy=http://<proxy_addr>:<proxy_port>
https_proxy=http://<proxy_addr>:<proxy_port>

Then, restart the Snap daemon using the command:

$ sudo systemctl restart snapd
Can I create configuration files specifically for the Snap service?

Yes, you can create configuration files specifically for the Snap service. First, create a folder for the Snap daemon using the command:

$ sudo mkdir -p /etc/systemd/system/snapd.service.d/

Then, create configuration files for the environment variables using the commands:

$ echo -e '[Service]\nEnvironment="http_proxy=http://<proxy_addr>:<proxy_port>/"' | sudo tee /etc/systemd/system/snapd.service.d/http-proxy.conf
$ echo -e '[Service]\nEnvironment="https_proxy=http://<proxy_addr>:<proxy_port>/"' | sudo tee /etc/systemd/system/snapd.service.d/https-proxy.conf

Finally, reload the daemon and restart Snapd with the commands:

$ sudo systemctl daemon-reload
$ sudo systemctl restart snapd
How can I edit the Snapd configuration file directly?

To edit the Snapd configuration file directly, open the file /etc/sysconfig/snapd in a text editor using the command:

$ sudo vim /etc/sysconfig/snapd

Add the following lines to the file:

http_proxy=http://<proxy_addr>:<proxy_port>
https_proxy=http://<proxy_addr>:<proxy_port>

Save the file and exit the text editor.

Are there any specific versions of Ubuntu or Snapd where these methods may not work?

While these methods should work for most versions of Ubuntu and Snapd, it’s always a good idea to check the documentation for your specific version if you encounter any issues. Canonical provides detailed documentation for Snapd installation and configuration, which can be helpful in troubleshooting version-specific problems.

Where can I find more information or assistance if I have further questions?

If you have further questions or need more assistance, you can refer to the official documentation for Snapd on the Canonical website. Additionally, you can leave your questions or comments in the comments section of the article, and the author or other readers may be able to provide further guidance.
