Homebrew Installed Azure CLI not working - ValueError: field 6 out of range (need a 48-bit value)

[mark-read-coriel]

Having installed azure-cli via homebrew I get the following python errors whenever I try and run a command. e.g. if I perform az login, or az --help, or other commands I get the following errors:-

$ az login

Environment summary

Install Method (e.g. pip, interactive script, apt-get, Docker, MSI, edge build) / CLI version (az --version) / OS version / Shell Type (e.g. bash, cmd.exe, Bash on Windows)

I installed via home-brew, having initially tried to install using the curl method, however this failed to build. The home-brew version installed fine, but just doesn't work.

Running into the same issue here. This looks related to uuid.py from the python framework getting a 64 bit hardware address for the loopback adapter in High Sierra, specifically in _ifconfig_getnode(). The function expects a 48 bit mac address, but is instead getting 64 bits back and converting it to an int value that is too long for the subsequent call in uuid.py.

This is a sample output of the call to ifconfig that is being parsed:

b'lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384\n'
b'\toptions=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>\n'
b'\tinet 127.0.0.1 netmask 0xff000000 \n'
b'\tinet6 ::1 prefixlen 128 \n'
b'\tlladdr 70:cd:60:ff:ab:cd:ef:12 \n'

As you can see, the lladdr is longer than the usual 48 bit mac address. This issue should ideally be addressed in the uuid.py module from the python project.

I've created an issue in bugs.python.org for this: https://bugs.python.org/issue32502

Did anyone find a solution?

@derekbekoe, ty for the linkup to this ticket, sir. I missed this open status in my initial search. Any findings, I shall post back here.

[derekbekoe]

If anyone has steps to reproduce, it would help us provide a fix for this.

Same issue here. This blocks all our automated script and make impossible to work on Azure.

My output for az login is:

@derekbekoe

I suggest to mock the uuid call in a unit test to reproduce, as per https://bugs.python.org/issue32502 seems related to a new minor release of High Sierra and the network interface hardware. So, my guess is that there is no simple way to reproduce.

[lordgordon]

Currently the upstream Python issue has been fixed and merged (1). Unfortunately a new 3.6 release (3.6.5) is not due until the end of March 2018 (2).

Workaround for Python 3.6.4

A risky workaround is possible manually substituting the uuid.py module in your local installation of Python 3.6.4.

1. download the patched uuid.py from the approved PR: https://raw.githubusercontent.com/bbayles/cpython/d4b98dff3441c79fb7c2af9149b96f819d0c81ab/Lib/uuid.py
2. go to the proper library folder for your Python 3.6.4 installation. In my case is /usr/local/Cellar/python3/3.6.4_2/Frameworks/Python.framework/Versions/3.6/lib/python3.6;
3. make a copy of uuid.py: cp uuid.py uuid.py.orig;
4. substitute the file with the one download: cp /your/download/path/uuid.py ./uuid.py;
5. profit (az login and other az should now works as expected).

Created a PR that will switch to uuid4 if uuid1 raises the ValueError.
