I could get rid off generate-subunit: command not found error using:

sudo pip install -U os-testr

But hit yet another errors:

:) The new error is:

ovs-ofctl: br-tun is not a bridge or a socket
ovs-ofctl: br-ex is not a bridge or a socket

Well it turned out to be not so easy to get ready:

It report generate-subunit, when it come to fail, so it means other error

[Matt Riedemann (mriedem)]

I hit this too, I found out I had an error in my local.conf. I missed commented out a line, so double check your local.conf.

Noticed similar issue on Ubuntu VM

Tried this command too ie sudo pip install -U os-testr and then ./stack.sh , but still facing same issue

ved (ved-rajesh): Were you able to fix this problem? I am hitting the same error.

[Manjeet Singh Bhatia (manjeet-s-bhatia)]

this is not a bug actually,

it happens if devstack unable to install some packages like in my case it was enable to get liberasurecode-dev which led into that issue,

you to edit /etc/apt/source.list to enable install from trusty-backport (if ubuntu server) or xyz backports in case of other server

that fixed the issue for me.

[clayg (clay-gerrard)]

for me it was just not having a local.conf - weird failure mode...

[clayg (clay-gerrard)]

ah, so this is getting hit in the exit handler - if something fails before subunit get's installed (which is fairly late in the process) it blows up in the exit handler with command not found instead of highlighting the part that acctually failed - which was probably some sort of read_password thing if your local.conf was missing.

[Solomon (solly989)]

I just traced the error back and fixed as I went along. For me the error was:

+++lib/tls:source:43 hostname -f
hostname: Name or service not known
++lib/tls:source:43 DEVSTACK_HOSTNAME=
+++lib/tls:source:43 err_trap
+++./stack.sh:err_trap:517 local r=1
stack.sh failed: full log in /opt/stack/logs/stack.sh.log.2017-03-19-012504
Error on exit
./stack.sh: line 501: generate-subunit: command not found

so I went to lib/tls, line 43, and set removed the -f from my hostname command. Running 'hostname -f' in the shell returned an error.
