There is insufficient free space on the boot filesystem to copy the new ISO file to.

1. Check the amount of available space on the boot filesystem by logging in to the boot shell and running the following command

# df -h | grep “boot-firmware”

A typical ISO file is about 800 – 900 MB so this amount of available space and a bit more will be required.

1. The logs and/or the journal of systemd might use up more space than intended. To free up space run

# journalctl --vacuum-time=1d

1. If there is still insufficient free space, then check the /var/log directory of the boot shell for any large log files and delete them. The following command will sort them by size with the largest at the bottom.

# ls -lSrh /var/log
