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 needed to take a directory which had already run git init and needed to create the remote origin on our main internal git server.
|
|
ssh git@gitserver cd ~git mkdir myrepo cd myrepo git --bare init exit cd myproject git push ssh://git@gitserver/home/git/myrepo +master:master cd .. mv myproject myproject.orig git clone ssh://git@gitserver/home/git/myrepo myproject cd myproject |

Decided to go for it and dive into the world of the WordPress block editor based on the improvements in version 5.4 –
First, the upgrade went smoothly.
Second, switching to the new block editor was easy.
Third, making this post seems pretty painless. I disabled full-screen mode because I simply don’t like it ;-}
The post preview worked well, too.
Nice job, WP Team!

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 |

I needed to use an iframe between a pre-defined header and footer that would auto-fill the full height on any size screen.
On a desktop, the combined height of the header + footer was 223px and for mobile was 157px, so below find the CSS example:
calc(100vh - 223px) – for desktop
calc(100vh - 157px) – for mobile
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
... <style> @media only screen and (max-device-width : 480px) { #theiframe { width: 100%; height: calc(100vh - 157px); margin: 0; padding: 5px; display: block; } } #theiframe { width: 100%; height: calc(100vh - 223px); margin: 0; padding: 5px; display: block; } </style> ... <nav> ... </nav> <div class="doccontent"> <iframe src="https://www.yourdomain.com" id="theiframe"></iframe> </div> <footer> ... </footer> ... |

Using PERL, we can easily do a search and replace across multiple files.
perl -ni -w -e 'print unless m/^gdb\d+/;' yourFileSpec
