This document (000021244) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP4
SUSE Linux Enterprise for SAP Applications 15 SP4
Microsoft Azure

Situation

Standard SLES and SLES for SAP workloads running SLES 15 SP4 are unable to connect to the PAYG update infrastructure and an Azure instance re-registration fails.

Force new registration of the Azure instance: 
# registercloudguest --force-new

2023-10-20 07:36:23 <3> sles-15-sp4-gen2(22101) [zypper] refresh.cc(refreshRepositories):263 Skipping repository 'Basesystem_Module_x86_64:SLE-Module-Basesystem15-SP4-Pool' because of the above error.

Resolution

1. For testing set the environment variable "REQUESTS_CA_BUNDLE" while forcing a re-registration:

sles-15-sp4-gen2:~ # REQUESTS_CA_BUNDLE=/var/lib/ca-certificates/ca-bundle.pem registercloudguest --force-new
Registration succeeded

2. For testing set the environment variable "REQUESTS_CA_BUNDLE" while repositories metadata get refreshed - Example (truncated output):

sles-15-sp4-gen2:~ # REQUESTS_CA_BUNDLE=/var/lib/ca-certificates/ca-bundle.pem zypper ref
Retrieving repository 'SLE-Module-Basesystem15-SP4-Pool' metadata .............................................................................................................................................[done]
Building repository 'SLE-Module-Basesystem15-SP4-Pool' cache ..................................................................................................................................................[done]

3. Verify the symbolic link of the TLS CA certificate bundle - Note: Correct symbolic link is shown:

sles-15-sp4-gen2:~ # ll /etc/ssl/ca-bundle.pem
lrwxrwxrwx 1 root root 38 Apr 8 2021 /etc/ssl/ca-bundle.pem -> /var/lib/ca-certificates/ca-bundle.pem

4. Verify installed files from the "python3-certifi" package - Example  the "pip" command was used to install the package:

sles-15-sp4-gen2:~ # rpm --verify python3-certifi
.......T. /usr/lib/python3.6/site-packages/certifi/__init__.py
.......T. /usr/lib/python3.6/site-packages/certifi/__main__.py
S.5....T. /usr/lib/python3.6/site-packages/certifi/__pycache__/__init__.cpython-36.pyc
S.5....T. /usr/lib/python3.6/site-packages/certifi/__pycache__/__main__.cpython-36.pyc
S.5....T. /usr/lib/python3.6/site-packages/certifi/__pycache__/core.cpython-36.pyc
S.5....T. /usr/lib/python3.6/site-packages/certifi/core.py

From the "rpm" man page

S file Size differs
 M Mode differs (includes permissions and file type)
 5 digest (formerly MD5 sum) differs
 D Device major/minor number mismatch
 L readLink(2) path mismatch
 U User ownership differs
 G Group ownership differs
 T mTime differs
 P caPabilities differ


Resolution: When "python3-certifi" package was not installed from SUSE "SLE-Module-Basesystem15-SP4-Update" repository

1. Upload the original SUSE package "python3-certifi-2018.1.18-150000.3.3.1.noarch.rpm" and force a re-installation:

sles-15-sp4-gen2:/tmp # zypper --no-refresh --no-remote --non-interactive install -f python3-certifi-2018.1.18-150000.3.3.1.noarch.rpm


Additional verification -> When the SUSE provided "python3-certifi" package is installed

2. Verify the symbolic link of the TLS CA certificate bundle - Note: Correct symbolic link is shown:

sles-15-sp4-gen2:~ # ll /etc/ssl/ca-bundle.pem
lrwxrwxrwx 1 root root 38 Apr 8 2021 /etc/ssl/ca-bundle.pem -> /var/lib/ca-certificates/ca-bundle.pem


3. Verify and if needed adjust the function "where()" in file "/usr/lib/python3.6/site-packages/certifi/core.py"

   Example: Function from non-working "pip" installed "python3-certifi" package:

def where():
  f = os.path.dirname(__file__)
  return os.path.join(f, 'cacert.pem')


Example: Function from working SUSE repository provided "python3-certifi" package:

def where():
  f = os.path.dirname(__file__)
  return "/etc/ssl/ca-bundle.pem"

4. Force a re-registration

sles-15-sp4-gen2:~ # registercloudguest --force-new
Registration succeeded
5. Refresh the metadata of the repositories - Example (truncated output): 
sles-15-sp4-gen2:~ # zypper ref
Retrieving repository 'SLE-Module-Basesystem15-SP4-Pool' metadata .............................................................................................................................................[done]
Building repository 'SLE-Module-Basesystem15-SP4-Pool' cache ..................................................................................................................................................[done]

Cause

The "python3-certifi" package was not installed from SUSE "SLE-Module-Basesystem15-SP4-Update" repository.

The TLS CA certificate bundle "/usr/lib/python3.6/site-packages/certifi/cacert.pem" is used by non SUSE "python3-certifi" package and the function "where()" in file "/usr/lib/python3.6/site-packages/certifi/core.py" is using a different code.
