apt – Cannot install or reinstall certificates

On my jenkins/jenkins container (which I presume is running on top of an Ubuntu image), I’m getting an error while curl any https site, such as https://www.google.com, as below:

* error setting certificate verify locations:
  CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: /etc/ssl/certs

Googling some answers, I decided to reinstall my ca-certificates package. Fact is, whenever I run

apt install ca-certificates –reinstall

I get the following error:

Unpacking ca-certificates (20200601~deb9u1) ...
dpkg: error processing archive /var/cache/apt/archives/ca-certificates_20200601~deb9u1_all.deb (--unpack):
 unable to install new version of './etc/ssl/certs': No such file or directory
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/openssl_1.1.0l-1~deb9u2_amd64.deb
 /var/cache/apt/archives/ca-certificates_20200601~deb9u1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I even tried removing and installing the package to no avail: same error.
