Failed to scan repository for git repository which certificate is signed by Let's Encrypt

[JohnNiang]

What's happened?

Please see the following screenshot:

I found that ca-certificates insider ks-jenkins image is too old, below is my evidence:

root@devops-jenkins-7df59b847c-jhvtw:/# apt-get upgrade ca-certificates
Reading package lists... Done
Building dependency tree
Reading state information... Done
ca-certificates is already the newest version (20200601~deb9u1).
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I can confirmed that it's useful after we update ca-certificates insider ks-jenkins image.

Temporary solution

Execute commands below inside ks-jenkins container.

apt update
apt upgrade -y ca-certificates
