Understanding the Error Message

The error message "Failed to start clean up any mess left by 0dns-up" is a cryptic message that does not provide much information about the underlying cause of the issue. However, it is related to the DNS (Domain Name System) service, which is responsible for resolving domain names to IP addresses. The "0dns-up" part of the message suggests that the DNS service is not functioning correctly, and the system is unable to clean up any mess left behind by a failed DNS operation.

However, this may not be enough to resolve the issue. You can try running the update and upgrade commands separately to ensure that the system is up-to-date:

sudo apt-get update

Step 2: Check the DNS Service

The DNS service is responsible for resolving domain names to IP addresses. You can check the status of the DNS service by running the following command:

sudo journalctl -u systemd-resolved

This will display the system logs related to the DNS service. You can search for any error messages or warnings that may indicate the cause of the issue.

Step 4: Reconfigure the DNS Service

If the DNS service is not functioning correctly, you may need to reconfigure it. You can try reconfiguring the DNS service by running the following command:

sudo dpkg-reconfigure resolvconf

This will reconfigure the DNS service and may resolve the issue.

Step 5: Re the DNS Service

If none of the above steps resolve the issue, you may need to reinstall the DNS service. You can try reinstalling the DNS service by running the following command:

sudo apt-get install --reinstall resolvconf

This will reinstall the DNS service and may resolve the issue.
