Add sudo, dotnet SDK build need this to reduce risk of sdk build failure

[wli3]

We (SDK) hope to add sudo to build in docker image. So we do not need to download during CI build to reduce build failure like this.

LGTM - I just have one minor comment.

[MichaelSimons]

@wli3 - Can you merge in latest and address the one comment so that the PR can get merged?

[wli3]

Sorry for the delay just rebased

[wli3]

@dotnet-bot test opensuse please

[wli3]

opensuse failure seems unrelated. any idea?

[MichaelSimons]

the opensuse failure is something that recently regressed because the base image is no longer available - #97.

[wli3]

#97 is still opening. I will check a few days later again

[MichaelSimons]

wli3 - can you sync with the latest? CI should be fixed now.

[wli3]

Just updated

[MichaelSimons]

Unfortunately debian:8 regressed today - see #107.

[MichaelSimons]

@wli3 - The debian:8 issue was resolved. Can you please update the PR. I sure hope this is the last time 😃
