My attempts to build unofficial ROMs in the last week or two have failed as described in this thread .
@Manoj has used the latest docker image to successfully build a Pie ROM, but I don’t know whether anyone else has managed to produce a Nougat ROM. My last successful build was a Nougat ROM on 11th May for Sony Xperia Z5 Compact (suzuran).
I will experiment with a Pie build (for a device known to support Pie) to check that my build environment is OK.
Thanks for any advice
