Actual behavior

error at dotnet paket restore

Known workarounds

remove **/obj/ from .dockerignore

Start with the supplied Dockerfile and root .dockerignore, then inspect .paket/Paket.Restore.targets around line 171. Reproduce with the listed docker build command, compare behavior when **/obj/ is excluded or included, and consider the issue done when dotnet paket restore completes successfully during the image build.
