      Getting this error on my salt-master (CentOS 7), which is causing it to not being able to start.

      salt-master version ? and was it from repo of salt or packages of centos ?

      I think getting the repo from salt is better

        It is obviously waiting for opponent for a fight to the death.

          Well, the last part of the error says cannot open shared object file: No such file or directory. So something relating to that I'd assume.

            salt-master is 2018.3.1, used the bootstrap install so salt repo.

              You seem to miss some encryption libs...

                It does look like it, but why? Several months of everything working properly.

                Tried forcing the reinstall of the salt and salt-master packages but still no luck.

                  Any recent updates before you noticed it not working?

                    I encountered the same problem today upgrading from salt-minion-2017.7.5-1 to salt-minion-2017.7.6-1 on an Redhat Enterprise Linux 7.
                    The minion won't start and doesn't log anything.
                    systemctl tells about:
                    salt-minion: error: Failed to load configuration: Cannot load native module 'Cryptodome.Cipher._raw_des': Trying '_raw_des.so': /usr/li...

                    I guess the problem is not staltstack itself but the Cryptodome lib that received an update aswell.

                    python -m Cryptodome.SelfTest
Traceback (most recent call last):
  File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main

  File "/usr/lib64/python2.7/site-packages/Cryptodome/Util/_raw_api.py", line 191, in load_pycryptodome_raw_lib
    raise OSError("Cannot load native module '%s': %s" % (name, ", ".join(attempts)))

                    After downgrading to the previous version, salt-minion (2017.7.6-1) starts again.

                    yum downgrade python2-pycryptodomex-3.4.3-2.el7.x86_64

                    However downgrading that package is only a workaround and it will hopefully be fixed soon.

                      This is my current python2-pycryptodomex installed package, will try to downgrade as well to test it out.

Description : PyCryptodome is a fork of PyCrypto. It brings the following
            : enhancements with respect to the last official version of PyCrypto
            : (2.6.1):
            : 
            : * Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
            : * Accelerated AES on Intel platforms via AES-NI
            : * First class support for PyPy
            : * Elliptic curves cryptography (NIST P-256 curve only)
            : * Better and more compact API (nonce and iv attributes for
            :   ciphers, automatic generation of random nonces and IVs,
            :   simplified CTR cipher mode, and more)
            : * SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
            : * Salsa20 and ChaCha20 stream ciphers
            : * scrypt and HKDF
            : * Deterministic (EC)DSA
            : * Password-protected PKCS#8 key containers
            : * Shamir’s Secret Sharing scheme
            : * Random numbers get sourced directly from the OS (and not from a
            :   CSPRNG in userspace)
            : * Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
            : * Major clean ups and simplification of the code base
            : 
            : PyCryptodome is not a wrapper to a separate C library like
            : OpenSSL. To the largest possible extent, algorithms are
            : implemented in pure Python. Only the pieces that are extremely
            : critical to performance (e.g. block ciphers) are implemented as C
            : extensions.
            : 
            : Python 2 version.

                          Downgraded the package using the full address to the previous version in the salt repo:

                          yum downgrade https://repo.saltstack.com/yum/redhat/7/x86_64/2016.11/python2-pycryptodomex-3.4.3-2.el7.x86_64.rpm

                          Fixes associated with Salt 2018.3.1 for Python 2 and Python 3 on Redhat 7 & 6 have been sent to QA.

                            Don't know about CentOS, but the fixed Salt packages hit the Fedora repos in the last few hours.
