LXC conf SSD 150Go Ram 16Go ubuntu 24.04.2 LTS

  git clone https://github.com/telekom-security/tpotce
  cd tpotce

Failed here :

If I try "hwclock --hctosys" command :

echelon@TpotCeLight:~/tpotce$ hwclock --hctosys
hwclock: Cannot access the Hardware Clock via any known method.

Any idea how to debug/fix this issue ?

Hey Richard!
Didn't the installer continue after the error message? I tried to install T-Pot in a Proxmox LXC container (Debian 13) today and it worked after some tweaking. The time sync failure also occurred, but the installer just proceeded to the next step. If you are interested, I wrote a guide:

Hi,

With a Debian 13 installation, the setup was completed successfully, and the operation was initially fine, but the server would crash after 24 or 48 hours. The programmed CRON job for the reboot was incorrect/not working.

The documentation recommended installing a Debian 13 net install (or Debian 13 netinst).

Since the installation using the Debian 13 net install, there have been no more problems, and the Tpotce is stable.

Thank you for your tutorial.

Regards,

Richard

Hey,
thanks for your reply. My installation with the Debian 13 template is running for more than 48 hours now and did not crash yet. But if it ever starts to behave weird, I'll try the net install as well.
