Centos 8 not updating

 Ref: https://www.digitalocean.com/community/questions/cento-os-8-not-updating

Error: signature hdr data: BAD

I’ve reported this however for the time being what you can do is to update rpm alone and then do the dnf update on all packages;

dnf update rpm

After that is completed:

dnf update

 

CentOS through a VM - no URLs in mirrorlist

 

Ref: https://stackoverflow.com/questions/70926799/centos-through-a-vm-no-urls-in-mirrorlist

Check out this article: CentOS Linux EOL

The below commands helped me:

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-Linux-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-Linux-*

Doing this will make DNF work, but you will no longer receive any updates.

To upgrade to CentOS 8 stream:

sudo dnf install centos-release-stream -y
sudo dnf swap centos-{linux,stream}-repos -y
sudo dnf distro-sync -y

Optionally reboot if your kernel updated (not needed in containers).

How To Install OpenSSL 1.1.1 on CentOS 7

This tutorial goes through how to install openssl 1.1.1 on CentOS 7, since the yum repo only installs up to openssl 1.0.

Requirements

Upgrade the system

yum -y update

Install required packages

yum install -y make gcc perl-core pcre-devel wget zlib-devel

Download the latest version of OpenSSL source code

wget https://ftp.openssl.org/source/openssl-1.1.1k.tar.gz

Configure, build and install OpenSSL

Uncompress the source file

tar -xzvf openssl-1.1.1k.tar.gz

Change to the OpenSSL directory

cd openssl-1.1.1k

Configure the package for compilation

./config --prefix=/usr --openssldir=/etc/ssl --libdir=lib no-shared zlib-dynamic

Compile package

make

Test compiled package

make test

Install compiled package

make install

Export library path

Create environment variable file

vim /etc/profile.d/openssl.sh

Add the following content

export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64

Load the environment variable

source /etc/profile.d/openssl.sh

Verify the OpenSSL version

[Gitlab] gitlab runner doesn`t work on a specific project

Ref: gitlab runner doesn`t work on a specific project

Error:

Fetching changes with git depth set to 50...
fatal: remote origin already exists.
fatal: git fetch-pack: expected shallow list
ERROR: Job failed: exit status 1

Solution:

Centos 7 ships with git version 1.8.3.1 . This version doesn't support commands like git fetch-pack . To fix this problem, you could update git on your server from the IUS repository. update git on Centos 7 to version 2 from third-party IUS repo

$ git --version
git version 1.8.3.1

sudo yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
sudo yum install git
