Download and Installing FTL fails

Download and with that installation of FTL fails on raspberry PI 4.

I tried to update my pi-hole as usual using sudo pihole -up in the terminal.

  [i] Checking for updates...
  [i] Pi-hole Core:	up to date
  [i] Web Interface:	up to date
  [i] FTL:		update available

  [i] FTL out of date, it will be updated by the installer.

The update has been interrupted with the following message

  [i] FTL Checks...
  [✓] Detected AArch64 (64 Bit ARM) architecture
  [i] Downloading and Installing FTL...curl: (22) The requested URL returned error: 503
sha1sum: pihole-FTL-arm64.sha1: No such file or directory
  [✗] Downloading and Installing FTL
   Error: Download of https://github.com/pi-hole/ftl/releases/latest/download/pihole-FTL-arm64 failed (checksum error)
  [✗] FTL Engine not installed

  Unable to complete update, please contact Pi-hole Support

Expected Behaviour:

I would expect the update as usual together with PI-Hole Core and Web Interface

  • Operating System: Linux 6.12.47+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.12.47-1+rpt1~bookworm (2025-09-16) aarch64 GNU/Linux
  • Raspberry Pi 4

Actual Behaviour:

See above:

Pi-hole is still working wit FTL 6.3.3

You are encountering a server error.

Wait some time and try again.

Indeed! Being patient brought the solution after 6 hours, and it worked again.
