I guess the upstream nova has updated its requirements.txt to drop support for python2 completely. Al has started digging into the work required to move our image builds to python3, but it’s going to be a multi-day effort.

We’re checking to see if there’s a temporary workaround to get this build working in the short term.

Subject: [Starlingx-discuss] Failed when build StarlingX docker images

Hi: 

 I have some problem as building the StarlingX docker image. 

 When I built stx-nova through build-stx-base.sh, the process was stuck, and leave the error log as below.

 Please offer me some suggestions.

 Many thanks.
