@György-Farkas : I was pointing to a possible enhancement wrt image distribution. Many sites distributing images such as iso, a txt file containing the checksum is usually made available. Please see the ubuntu download mirror: http://reflection.oss.ou.edu/ubuntu-release/20.04.1/ The SHA256SUMS file contains the hash of the iso's. Once we download the image with wget, we can compare the checksum in the workstation before using the image. The checksum validation is a one time process, anyways. I always keep the images in my workstation for future use. OpenWRT provides the checksum in the page itself: https://archive.openwrt.org/releases/18.06.7/targets/ramips/mt76x8/ which would require redesign the Omega repo. The ubuntu approach is simple. Whenever a new image is released, update the txt file by adding a single line entry.. Thanks..
