I ran letsencrypt-auto renew and got the following error:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
root@prod06b:/etc/httpd/conf.d # /root/letsencrypt/letsencrypt-auto renew Error: couldn't get currently installed version for /opt/eff.org/certbot/venv/bin/letsencrypt: Traceback (most recent call last): File "/opt/eff.org/certbot/venv/bin/letsencrypt", line 7, in <module> from certbot.main import main File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/certbot/main.py", line 2, in <module> from certbot._internal import main as internal_main File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/certbot/_internal/main.py", line 10, in <module> import josepy as jose File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/josepy/__init__.py", line 41, in <module> from josepy.interfaces import JSONDeSerializable File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/josepy/interfaces.py", line 7, in <module> from josepy import errors, util File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/josepy/util.py", line 7, in <module> import OpenSSL File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/OpenSSL/__init__.py", line 8, in <module> from OpenSSL import crypto, SSL File "/opt/eff.org/certbot/venv/local/lib/python2.7/dist-packages/OpenSSL/crypto.py", line 12, in <module> from cryptography import x509 ImportError: No module named cryptography |
The solution in this article gave me the answer:
|
|
sudo rm -rf /opt/eff.org/* sudo pip install -U certbot sudo certbot renew --debug |
Turns out Python was old at version 2.7, so did the following also:
|
|
sudo yum -y install python36 sudo alternatives --config python sudo pip install --upgrade pip |
Also had to change the cron job script to call certbot directly instead of letsencrypt-auto : vi /root/letsencrypt-cron.sh
|
|
#!/bin/sh # # letsencrypt-cron.sh # #OLD: if ! /root/letsencrypt/letsencrypt-auto renew > /var/log/letsencrypt/renew.log 2>&1 ; then #NEW: if ! /usr/bin/certbot renew > /var/log/letsencrypt/renew.log 2>&1 ; then echo Automated renewal failed: cat /var/log/letsencrypt/renew.log exit 1 fi apachectl graceful |

I tried upgrading pip when prompted to do so: sudo pip install –upgrade pip This worked, but removed the system install in /usr/bin/pip and replaced it with /usr/local/bin/pip – NOT GOOD! The solution is as follows:
|
|
/usr/local/bin/pip uninstall pip yum remove python27-pip yum install python27-pip |

|
PACKAGES=`yum list installed | grep php | awk -F. '{print $1}' | tr "\n\r" " "` echo $PACKAGES yum remove -y $PACKAGES |
~or~
|
|
yum remove php56 php56-cli php56-common php56-devel php56-gd php56-jsonc php56-jsonc-devel php56-mbstring php56-mcrypt php56-mysqlnd php56-pdo php56-pecl-imagick php56-process php56-xml |

The Problem Tried to install the latest version of cpan and got stuck. Tracked it down to the dependency module Mac::SystemDirectory which was failing to build:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |

The Solution Use the MacOS installer command to deploy the needed files:
|
|
xcode-select --install sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / installer: Package name is macOS_SDK_headers_for_macOS_10.14 installer: Installing at base path / installer: The install was successful. |
The, rerunning the cpan install works:
|
|
cpan[1]> install Mac::SystemDirectory ... Running make install Files found in blib/arch: installing files in blib/lib into architecture dependent library tree Installing /Library/Perl/5.18/darwin-thread-multi-2level/auto/Mac/SystemDirectory/SystemDirectory.bs Installing /Library/Perl/5.18/darwin-thread-multi-2level/auto/Mac/SystemDirectory/SystemDirectory.bundle Installing /Library/Perl/5.18/darwin-thread-multi-2level/Mac/SystemDirectory.pm Installing /usr/local/share/man/man3/Mac::SystemDirectory.3pm Appending installation info to /Library/Perl/Updates/5.18.2/darwin-thread-multi-2level/perllocal.pod ETHER/Mac-SystemDirectory-0.10.tar.gz /usr/bin/make install -- OK |
