Check for OS upgrade to Ubuntu automatically everyday.
Here’s a single script that will update your system and schedule the do-release-upgrade command to run at 12:30 AM every day: #!/bin/bash # Update and upgrade the system sudo apt update sudo apt upgrade -y # Create the upgrade script cat << EOL > ~/upgrade.sh #!/bin/bash sudo apt update sudo apt upgrade -y sudo do-release-upgrade -f DistUpgradeViewNonInteractive EOL # Make the upgrade script executable chmod +x ~/upgrade.sh # Schedule the upgrade script to run at 12:30 AM every day (crontab -l 2>/dev/null; echo "30 0 * * * /home/your_username/upgrade.sh" ) | crontab - echo "Upgrade script created and scheduled to run at 12:30 AM every day." Replace your_username with your actual username in the script. This script will update and upgrade your system, create the upgrade.sh script, make it executable, and schedule it to run at 12:30 AM every day using cron.
