Task was failing on deploying upgrade for Ubuntu.
Failed add prefetch item {concatenation " ; " of lines of file “EDR_PackageList.txt” of folder (parameter “edrdir”)}
After inspecting the packages and the ResolverDependancies.sh we found this line
pkginfo=$(grep -h -A3 -m 1 /$pkgnameinfo “$package_file”)
The A3 was olnly looking down the package item to SHA1 and missing SHA256 so the output was malformed in the EDF package file and not including the SHA256 value and failing there.
