When attempting to upgrade SSB the following error may be reported
Error during upgrade - tar: ………… Cannot write: No space left on device; tar: Exiting with failure status due to previous errors
There is insufficient free space on the boot filesystem to copy the new ISO file to.
# 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.
# journalctl --vacuum-time=1d
# ls -lSrh /var/log
