Ensure the network connection is functioning properly: Check if the network connection is working, and try using the ping command to test if the domain name can be resolved. 2. Check the DNS configuration: Verify if the system&#8217;s DNS configuration is correct. You can edit the \/etc\/resolv.conf file and add the correct DNS server address using the following command.<\/p>\n<pre class=\"post-pre\">&nbsp;&nbsp;sudo&nbsp;nano&nbsp;\/etc\/resolv.conf<\/pre>\n<p>3. Update software sources: There may be an issue with the software source configuration causing domain name resolution to fail. You can use the following command to update the software source configuration.<\/p>\n<pre class=\"post-pre\">&nbsp;&nbsp;sudo&nbsp;apt-get&nbsp;update<\/pre>\n<p>Check the firewall settings: Sometimes firewalls can block domain resolution requests, you can try temporarily turning off the firewall and reinstalling gcc.<\/p>\n<pre class=\"post-pre\">&nbsp;&nbsp;sudo&nbsp;ufw&nbsp;disable<\/pre>\n<p>Using a proxy server: If the network environment requires accessing through a proxy server, you can configure the address and port of the proxy server so that the system can resolve domain names correctly. If none of the above methods work, it may be due to issues with the network environment or DNS server. In that case, you can try changing the network environment or using another reliable DNS server.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you encounter issues resolving domain names while installing gcc on Ubuntu, you can try the following solutions: 1.
