I went to perform a yum update and got the following error:
Retrieving key from file : ///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
The GPG keys listed for the "MySQL 5.7 Community Server" repository are already installed but they are not correct for this package .
Check that the correct key URLs are configured for this repository .
Failing package is : mysql - community - server - 5.7.37 - 1.el7.x86_64
GPG Keys are configured as : file : ///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
SOLUTION: Import the needed new key and manually edit the config files before retrying the yum update.
rpm -- import https : //repo.mysql.com/RPM-GPG-KEY-mysql-2022
I had to edit two files: mysql-community-source.repo and mysql-community.repo
For 5.7 – add -2022 to the key name: i.e.: ORIGINAL:
gpgkey = file : ///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
MODIFY ONE […]

Problem While running the aws cli command from a Perl async command inside apid, I go the following error:
IOError : [ Errno 10 ] No child processes
Solution The issue turned out to be a bug in Python2.7, so I upgraded to Python3.4, then uninstalled and re-installed the aws cli software so that it used the proper Python34 version. Procedure

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

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

PROBLEM DEFINITION Bamboo Catalina error found in catalina.out:
- Djava . endorsed . dirs = / volumes / data / bamboo / current / endorsed is not supported . Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules .
Error : Could not create the Java Virtual Machine .
Error : A fatal exception has occurred . Program will exit .
SOLUTION SUMMARY Correct by using Java 8 instead. Do it manually using alternatives –set, or interactively using alternatives –config. MANUAL PROCEDURE – two steps, one for java and one for javac
alternatives -- set java / usr / lib / jvm / jre - 1.8.0 - openjdk . x86_64 / bin / java
alternatives -- set javac / usr / lib / jvm / jre - 1.8.0 - openjdk . x86_64 / bin / javac
INTERACTIVE PROCEDURE – two steps, one for java and one for javac

To remove a specific package without its dependencies use rpm:
rpm - qa | grep pecl
rpm - e -- nodeps php55 - pecl - jsonc php55 - pecl - jsonc - devel
As always, YMMV!

As usual, whenever I have to do sysadmin on a Ubuntu-based OS, I find problems. When will people realize what a horrible OS it is? In this case, packages needed were unavailable. For apt-get to function, the file /etc/apt/sources.list must be edited to change all URLs from security.ubuntu.com and archive.ubuntu.com to old-releases.ubuntu.com, using the sed […]
