Curl configuration overriden after compilation. HTTPS disabled

In order to work on a old legacy project, I try to setup a docker image base on ubuntu 20.04 using an old version of curl 7.27.0.

So I install curl from sources

ENV CURL_VERSION 7.27.0
RUN cd /tmp &&  \
wget "https://curl.se/download/curl-$CURL_VERSION.tar.gz" -O curl.tgz && \
tar -xvzf curl.tgz && \
cd curl-$CURL_VERSION && \
./configure --with-Secure-Transport --enable-libcurl-option && \
make && make install

The installation succeed, and can see that the curl version is the following

curl 7.27.0 (x86_64-unknown-linux-gnu) libcurl/7.68.0 OpenSSL/1.1.1f zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.2.0) libssh/0.9.3/openssl/zlib nghttp2/1.40.0 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp scp sftp smb smbs smtp smtps telnet tftp 
Features: AsynchDNS IDN IPv6 Largefile NTLM NTLM_WB SPNEGO SSL libz TLS-SRP

We can see that the protocols https is in the list of active protocols.

Then, some other commands run on the docker build, for example apt-get update or ldconfig etc..

Then when the next curl call is executed after, i got the following error:

curl: (1) Protocol "https" not supported or disabled in libcurl

So when i check again the curl version, i see this:

curl 7.27.0 (x86_64-unknown-linux-gnu) libcurl/7.27.0 zlib/1.2.11
Protocols: dict file ftp gopher http imap ldap pop3 rtsp smtp telnet tftp 
Features: IPv6 Largefile libz

It seems that some protocols has been disabled after running apt update or ldconfig and that the libcurl version have been downgraded to the same version of curl.

I cannot understand why this is happening and what is causing this. So my question is, how can I prevent some protocoles to be disabled? or libcurl lib to be downgraded? Also, any though, explanation on what happened?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
