On Saturday 13th January 2018, Xubuntu 17.04 goes End of Life (EOL). For more information please see the Ubuntu 17.04 EOL Notice.
We strongly recommend upgrading to the current regular release, Xubuntu 17.10.1, as soon as practical. Alternatively you can download the current Xubuntu release and install fresh.
The 17.10.1 release recently saw testing across all flavors to address the BIOS bug found after its release in October 2017. Updated and bugfree ISO files are now available.
