Hi
I tried to install on my proxmox a TpotCe under a LXC and it failed
Proxmox Host CPU i7 7500 32Go SSD 500Go
LXC conf SSD 150Go Ram 16Go ubuntu 24.04.2 LTS

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

Failed here :

If I try "hwclock --hctosys" command :

echelon@TpotCeLight:~/tpotce$ hwclock --hctosys
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --verbose option to see the details of our search for an access method.

Any idea how to debug/fix this issue ?
