+====== Distro Upgrade ======
+Software Updater: "Not enough free disk space"
+Thread at Slack. First try "sudo apt-get autoremove --purge", and if that doesn't work, then to see the installed kernels:
+<code>

+And then choose the old ones (comparing with what's on /boot) to manually remove...
+<code>
+df -h /boot
+ls -l /boot
+# Install aptitude to see why it was installed... (Output wordy, says whether manually installed, dependencies)
+aptitude why -v linux-headers-5.11.0-46-generic
+sudo apt purge linux-headers-5.11.0-46-generic  # picked a few old looking ones
