How to install latest ca-certificates on Ubuntu 14 [closed]
Solution 1:
You can install the latest stable certs from source (you'll need a working wget
and unxz
or at least a way of copying the uncompressed .tar file or its contents onto your target server (perhaps just scp -r
once you've extracted it locally):
# Ensure dependencies
sudo apt -y install make tar xz-utils wget
# Make a place to build it in
mkdir -p ~/src
cd ~/src
wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/ca-certificates/20210119~20.04.2/ca-certificates_20210119~20.04.2.tar.xz
tar -xJf ca-certificates_20210119~20.04.2.tar.xz
# Now build and install
cd ca-certificates-20210119~20.04.1
make
sudo make install
# You might want to run this interactively to ensure
# you can select the ISRG Root X1
# in which case, just run: sudo dpkg-reconfigure ca-certificates
sudo dpkg-reconfigure -fnoninteractive ca-certificates
sudo update-ca-certificates
/usr/bin/c_rehash /etc/ssl/certs
