Storage commands failling on Fedora 35 when Python 3.6 is not present

[dem4gus]

Describe the bug

Any az storage commands fail on Fedora 35

Command Name az storage account list

Errors:

The command failed with an unexpected error. Here is the traceback:
'NoneType' object is not iterable

To Reproduce:

Steps to reproduce the behavior. Note that argument values have been redacted, as they may contain sensitive information.

• Start a new container using the Fedora image: docker run -it index.docker.io/library/fedora:35
• Install Azure CLI using instructions in Microsoft documentation
  • rpm --import https://packages.microsoft.com/keys/microsoft.asc
  • dnf install -y https://packages.microsoft.com/config/rhel/8/packages-microsoft-prod.rpm
  • dnf install azure-cli
• Login to an account
  • az login --use-device-code
• az storage account list

Expected Behavior

Available storage accounts in the subscription will be listed, or command will fail gracefully.

Environment Summary

Linux-5.16.19-200.fc35.x86_64-x86_64-with-glibc2.34, Fedora Linux 35 (Container Image)
Python 3.10.2
Installer: RPM

azure-cli 2.36.0

Additional Context

The same command with the same account succeeds when run from a container using mcr.microsoft.com/azure-cli.

This error is a blocker to my workflow so I started to roll back through the versions of azure-cli in the rpm repository to try to get it working. The command also failed in 2.35.0 but succeeded in 2.34.1. When I installed 2.34.1 dnf (using the 1.el7 repository instead of 1.el8, since only 2.35 and 2.36 are available in 1.el8) also resolved python3.6 as a dependency, which means it got installed on my system. After python3.6 was installed I ran az upgrade to return to Azure CLI 2.36.0, but the version of Python in use by Azure CLI is still 3.6.15. After returning to Azure CLI 2.36 with Python 3.6, the az storage commands are functioning because Python3.6 is still available for Azure CLI to use.

To summarize:

• Azure CLI <= 2.34.1 has libpython3.6m.so.1.0 listed as a dependency, which installs Python3.6:

  # dnf repoquery --requires azure-cli-2.34.1-1.el7
  Last metadata expiration check: 0:02:27 ago on Fri Apr 29 18:45:26 2022.
  ld-linux-x86-64.so.2()(64bit)
  ld-linux-x86-64.so.2(GLIBC_2.3)(64bit)
  libc.so.6(GLIBC_2.14)(64bit)
  libpthread.so.0()(64bit)
  libpthread.so.0(GLIBC_2.2.5)(64bit)
  libpython3.6m.so.1.0()(64bit)
  python3
  rtld(GNU_HASH

• Azure CLI > 2.34.1 does not have the library as a dependency, only python3, so the default installation of Python3.10 is enough to satisfy that requirement:

  # dnf repoquery --requires azure-cli-2.35.0-1.el7
  Last metadata expiration check: 0:02:41 ago on Fri Apr 29 18:45:26 2022.
  ld-linux-x86-64.so.2()(64bit)
  ld-linux-x86-64.so.2(GLIBC_2.3)(64bit)
  libc.so.6(GLIBC_2.14)(64bit)
  libpthread.so.0()(64bit)
  libpthread.so.0(GLIBC_2.2.5)(64bit)
  python3
  rtld(GNU_HASH)

• After upgrading from 2.34.1 using az upgrade, Python3.6 is still available:

  
  # az upgrade
  ...
  # az -v
  azure-cli                         2.36.0

Storage

[jiasli]

@dem4gus, it actually meets my expectation that the el8 package doesn't work for Fedora 35! 😂

We don't really have official support for fedora 35. The doc https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=dnf is somehow outdated.

Before we dive into this issue, you may install with pip to get unblocked quickly: https://github.com/Azure/azure-cli/issues/20476

Please let us know if it works for you.

[jiasli]

The problem is that why libpython3.6m.so.1.0()(64bit) is missing from the RPM's requirement since 2.35.0. We didn't change anything in the build process. 🤔

• https://github.com/Azure/azure-cli/blob/azure-cli-2.35.0/scripts/release/rpm/azure-cli.spec
• https://github.com/Azure/azure-cli/blob/azure-cli-2.35.0/scripts/release/rpm/pipeline.sh

There are the build logs for

• 2.34.1: https://dev.azure.com/azure-sdk/public/_build/results?buildId=1402865&view=logs&j=eefb80ef-df2c-51d4-a735-8b3fa596bf12&t=6f9a8c49-480f-5696-065d-31253d9c4238
• 2.35.0: https://dev.azure.com/azure-sdk/public/_build/results?buildId=1475660&view=logs&j=aedd744b-2bf4-59d5-bada-b121261b4f81&t=adba5b8c-e58b-5021-0563-de243d1b6648

[jiasli]

Root cause

I manually binary-searched all builds on dev branch between 2.34.1 and 2.35.0, and saw libpython3.6m.so.1.0 was removed by 20220309.2 (triggered by commit 07819726e13d72587eb82b65c92ecba3bb009f32).

Requires: ld-linux-x86-64.so.2()(64bit) ld-linux-x86-64.so.2(GLIBC_2.3)(64bit) libc.so.6()(64bit) libc.so.6(GLIBC_2.14)(64bit) libc.so.6(GLIBC_2.2.5)(64bit) libc.so.6(GLIBC_2.3)(64bit) libc.so.6(GLIBC_2.3.2)(64bit) libc.so.6(GLIBC_2.3.4)(64bit) libc.so.6(GLIBC_2.4)(64bit) libc.so.6(GLIBC_2.6)(64bit) libc.so.6(GLIBC_2.7)(64bit) libffi-c643fa1a.so.6.0.4()(64bit) libpthread.so.0()(64bit) libpthread.so.0(GLIBC_2.2.5)(64bit) rtld(GNU_HASH)

By comparing 20220309.2 with previous build 20220308.33, I noticed wrapt was bumped:

- wrapt-1.11.2
+ wrapt-1.14.0

Then by backtracking PRs before 07819726e13d72587eb82b65c92ecba3bb009f32, I saw #21557 removed the limitation on wrapt, which has dependency on libpython3.6m.so.1.0()(64bit). This can be verified with /usr/lib/rpm/find-requires:

> docker run -it --rm centos:centos7

# yum install -y wget rpm-build gcc libffi-devel python3-devel openssl-devel make bash coreutils diffutils patch dos2unix python3-virtualenv
# python3 -m venv cli-env
# . cli-env/bin/activate
# pip install -U pip
# pip install wrapt==1.11.2

# cd cli-env
# find -name *.so
./lib/python3.6/site-packages/wrapt/_wrappers.cpython-36m-x86_64-linux-gnu.so

# find -name *.so | /usr/lib/rpm/find-requires
libc.so.6()(64bit)
libc.so.6(GLIBC_2.2.5)(64bit)
libc.so.6(GLIBC_2.4)(64bit)
libpthread.so.0()(64bit)
libpython3.6m.so.1.0()(64bit)

To Do

There is only python3 on CentOS7, but no python3.6, so there is no simple way to pin Python to python3.6 for RPM built with CentOS 7. Actually, it is a bad practice to build RPM on one system (CentOS 7) and install/run it on another system (Fedora 35).

To completely solve this problem, we should use Fedora 35 to build an RPM and install that RPM on Fedora 35 (https://github.com/Azure/azure-cli/issues/22278).

[jiasli]

A workaround (credit to @bebound. Thanks!) is to specify python36 here:

https://github.com/Azure/azure-cli/blob/4223f08e758e9fe16223564ba9fc77aee6315751/scripts/release/rpm/azure-cli.spec#L28

python36 is not a package name, but a capability provided by python3 or python 3.6 package.

On Fedora 35:

# dnf repoquery --provides python3.6
Last metadata expiration check: 0:11:48 ago on Fri May  6 09:11:57 2022.
bundled(libmpdec) = 2.4.2
bundled(mpdecimal) = 2.4.2
libpython3.6m.so.1.0
libpython3.6m.so.1.0()(64bit)
pkgconfig(python-3.6) = 3.6
pkgconfig(python-3.6m) = 3.6
python3.6 = 3.6.15-1.fc35
python3.6 = 3.6.15-2.fc35
python3.6(x86-32) = 3.6.15-1.fc35
python3.6(x86-32) = 3.6.15-2.fc35
python3.6(x86-64) = 3.6.15-1.fc35
python3.6(x86-64) = 3.6.15-2.fc35
python36 = 3.6.15-1.fc35
python36 = 3.6.15-2.fc35

On CentOS 7:

# yum -y install yum-utils
# repoquery --provides python3
python(abi) = 3.6
python3 = 3.6.8-18.el7
python3(x86-32) = 3.6.8-18.el7
python36 = 3.6.8-18.el7
python36(x86-32) = 3.6.8-18.el7
python(abi) = 3.6
python3 = 3.6.8-18.el7
python3(x86-64) = 3.6.8-18.el7
python36 = 3.6.8-18.el7
python36(x86-64) = 3.6.8-18.el7

Since Python 3.6 is now deprecated, the better solution is to build RPMs with the latest Fedora.

This is because Python 3.10 is used to import Python 3.6 libraries which are not compatible.
