Sub-process /usr/bin/dpkg returned an error code (1)

This error message typically indicates that there was an issue with the package manager, dpkg, during an installation or upgrade of a package. The error code (1) suggests there was a failure during the process.

To troubleshoot this issue, you can try the following steps:

1. Check the error message for more details on what went wrong. Look for any specific error codes or messages that might help you identify the issue.

2. Try running the installation or upgrade command again. Sometimes, a temporary issue can cause the process to fail.

3. Check if the package manager is locked or in use by another process. You can try running the command "sudo lsof /var/lib/dpkg/lock" to see if any other processes are using dpkg.

4. Check if there are any broken dependencies or conflicts with other packages. You can try running "sudo apt-get install -f" to fix any broken dependencies.

5. If none of the above steps work, you may need to remove the package causing the issue and reinstall it. You can try running "sudo apt-get remove [package_name]" followed by "sudo apt-get install [package_name]".

If you are still unable to resolve the issue, you may need to seek further assistance from a Linux support forum or community.
