Linux Cockpit Terminal screen illegible

Posted on by Jeff

If the Terminal screen on a server’s Cockpit page is illegible, you’ll need to set the site permissions from your client web browser.

Go to the site at http://x.x.x.x:9090, login, click the Terminal option.

Click the lock icon in the address bar.

Click on Connection Not Secure.

Click on More Information.

Click on the Permissions icon.

Under “Extract Canvas Data”, unselect “Use Default” and select “Allow”.

Refresh the page. You may have to change the font size.

Pre-Upgrade System Preparation

elevate to root

Create System Backup
mkdir mkdir /mnt/athena_backups/"$HOSTNAME"_backups
tar -czf /mnt/athena_backups/"$HOSTNAME"_backups/etc-backup-$(date +%Y%m%d).tar.gz /etc
dpkg --get-selections > /mnt/athena_backups/"$HOSTNAME"_backups/package-selections-$(date +%Y%m%d).txt
Ensure Debian 12 is fully updated before proceeding
apt update
apt upgrade -y
apt dist-upgrade -y
apt clean
apt autoremove -y
Verify system integrity before upgrade
apt --fix-broken install
dpkg --configure -a
Create safety copy of repository settings
cp /etc/apt/sources.list /etc/apt/sources.list.bookworm-backup
cp -r /etc/apt/sources.list.d /etc/apt/sources.list.d.bookworm-backup
Update Main Sources List and Additional Repositories
sed -i 's/bookworm/trixie/g' /etc/apt/sources.list
find /etc/apt/sources.list.d -name "*.list" -exec sed -i 's/bookworm/trixie/g' {} ;

This systematically updates all repository references from Bookworm to Trixie across all configuration files.

apt update

Third-party repositories may not immediately support Trixie. Consider temporarily disabling them by adding ‘#’ at the beginning of their lines in sources configuration files.

Minimal Upgrade First
apt upgrade --without-new-pkgs
Full Distribution Upgrade
apt full-upgrade
Confirm successful upgrade completion
cat /etc/debian_version
lsb_release -a
cat /etc/os-release
Clean Obsolete Packages
apt autoremove -y
apt autoclean
Update Package Cache
apt update
apt list --upgradable
System Reboot: Complete the upgrade process
systemctl reboot
