I am try to install DSM 7.1.0-42661 with RedPill 0.9.2.5 image on proxmox server. After successfully boot the loader and find the device on network, an error message prevent to finish installation (i attached screenshot). Failed to install DSM. Failed to install the file. The file is probably corrupted. Can anyone help me to solve this issue? I have tried many times to build this with no success. Thank you!
