Sorry all – I goofed when making a last minute change to the gui installer.
The issue is that synaptic and other apps that need root privileges will complain about
Failed to run synaptic as user root
Unable to copy the users’ Xauthorisation file
Also apt complains about tmp folder error after doing apt-get update
Quick fix for those that have already installed antiX17.3 (full or base).
In a root terminal type chmod 1777 /tmp
If you run live, or frugal, no need to do anything except simply wait for an upgrade to the installer to appear in the repos.
New bugfix isos for full and base are now available.
