Problem to update curl 7.36 / 7.38 on Debian 8 Jessie

For some unknown reason, curl on one of my machines works no more with https, and I don't know how I can upgrade it. This has happened unnoticedly last week.

Error message
From bash command line:

# curl https://localhost
curl: (1) Protocol https not supported or disabled in libcurl
#

Open in new window

(same for any host)

Version
I don't know why the version has now be changed to this https-less version

# curl -V
curl 7.36.0 (x86_64-unknown-linux-gnu) libcurl/7.36.0
Protocols: dict file ftp gopher http imap pop3 rtsp smtp telnet tftp 
Features: IPv6 Largefile

1 - Any idea how this version is now in place?
(no suspect ssh connection logged)

2 - I have tried unsuccessfully to uninstall / reinstall curl
Note that apt-get displays that the version is 7.38/amd64 while curl autoproclams to be 7.36/X86_64

3 - Any suggestion on how I could solve that by forcing some other version
- by directly installing (how?)
- by changing depot?

I ran the same thing on another computer, with the same Debian 8.10
Quite different pictures... so it really puzzles me....

Any suggestion or hint?

Finally solved by deleting some files which were in /usr/local, changing some links to libcurl, desinstalling curl and libcurl, purging dpkg caches and reinstalling.
Now at expected version for Jessie and all Ok.

Your ldd suggestion (and its results) have been essential to help me guessing some directions, thx!

Thx for thed comments which led me into the right direction

In your case there was a private library of libcurl in /usr/local... messing things up... Good you found it.
