steev 2025-07-29 21:39 manager ~0020760	What host OS are you running? Are you running this script in a VM? What happens if you set a mirror manually? The error message claims that the mirrors are in the middle of a sync, but if you're hitting this every single time, either you are very unlucky to always be trying to hit the mirrors when they are syncing, or potentially something on your network/ISP side is somehow blocking portions of the sync.

JR556 2025-07-29 22:33 reporter ~0020761	What host OS are you running? Kali 2025.2 fully updated Are you running this script in a VM? System 1 - baremetal intel System 2 - proxmox VM on Intel What happens if you set a mirror manually? Have not tried this, using default build.sh script from https://gitlab.com/kalilinux/build-scripts/kali-live The error message claims that the mirrors are in the middle of a sync, but if you're hitting this every single time, either you are very unlucky to always be trying to hit the mirrors when they are syncing, or potentially something on your network/ISP side is somehow blocking portions of the sync. I thought this could be the case on system 1, however on system 2 it is directly connected to the internet and i experienced the same issue. Note: i just re-ran our build script and the issue does not appear for the first of our 2 builds. Maybe a transient issue. No changes internally on script or network configuration.

JR556 2025-07-30 02:01 reporter ~0020762	Both builds successfully completed today. No changes have been made since the issues began so this may have been a transient error (or im just unlucky). Please close.
