Kops: brew install --HEAD kops fails (sha1sum command is not available)

[tcf909]

When trying to install (or upgrade) kops using brew I get:

"sha1sum command is not available" but I clearly have it installed on my system. This is a recent problem, as I have used --HEAD for awhile.

Cs-MacBook-Pro:~ tc.ferguson$ brew install --HEAD kops

@tcf909 I just checked this out on my system to verify, and you're correct. I also tried pulling from GitHub master directly and it's broken. I thought we fixed this one!

I am looking into a fix, but in the meantime if you need to install kops from HEAD and your system allows it, brew install md5sha1sum will install the utility that you need to compile. Sorry for your trouble and we will get this one fixed right up!

We tried to make changes to the brew formula to fix this, but it looks like you don't have the latest version of the formula available. I'm not exactly sure how homebrew works, maybe we need to push the latest changes to brew or something.

In the meantime, you can either brew install md5sha1sum and then brew install kops or you can brew edit kops and adjust your dependency section as follows. If you continue to have difficulties, please join us in #kops in the k8s slack and we'll help you debug.

...
depends_on "go" => :build
depends_on "kubernetes-cli"
depends_on "md5sha1sum"
...

@justinsb @kris-nova @chrislovecnm When we release 1.5.2, can we do a "this is how we actually release" session so we can all learn how to make the changes in our repo stick elsewhere?

Hey gang, I'm running into this problem also. I'm on a brand new Macbook. Doing a brew install md5sha1sum didn't help (same error as above), but adding it into the dependency section with brew edit kops did the trick.

Same here. brew install md5sha1sum did not fix the the issue.

... but adding to the dependency section of the formula worked for us as well.

[tcf909]

Same here. brew edit kops + adding dependency line 'depends_on
"md5sha1sum"' worked for me as well.
