first build on Linux: OpenSSL issue

[JoeCFD]

@mzimmers anti-virus application in Linux? I do not have any. But I know Linux viruses indeed exist.

I have libssl.so.3. You seem not having it.
run
sudo synaptic
Search for libssl
to see if you have installed libssl-dev
If not, install it. This one has version 3.0.2.

[mzimmers]

@JoeCFD I believe I do have it:

mzimmers@LinuxBoxZimmers:~/Downloads$ whereis libssl
libssl: /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/x86_64-linux-gnu/libssl3.so /usr/lib/x86_64-linux-gnu/libssl.a
mzimmers@LinuxBoxZimmers:~/Downloads$ cd /usr/lib/x86_64-linux-gnu/
mzimmers@LinuxBoxZimmers:/usr/lib/x86_64-linux-gnu$ ls -l libssl*
-rw-r--r-- 1 root root  382024 Feb 17  2023 libssl3.so
-rw-r--r-- 1 root root 1016494 Oct 10 02:03 libssl.a

mzimmers@LinuxBoxZimmers:/usr/lib/x86_64-linux-gnu$ 

The link just happens to be pointing to my older version. I don't know why.

[JoeCFD]

@mzimmers you do not have libssl.so.3 while you have libssl3.so.

[mzimmers]

@JoeCFD oops...good catch.

[JoeCFD]

@mzimmers
the latest ssl version is 3.0.2 in Jammy 22.04
https://launchpad.net/ubuntu/jammy/+source/openssl
I guess you need to upgrade your Ubuntu.

[mzimmers]

@JoeCFD what output do you get when you run this command:

ls -l /usr/lib/x86_64-linux-gnu/libssl*

And, since it appears that I have an older version of openssl, how do I go about removing the old version without disrupting the rest of my system?

[JoeCFD]

@mzimmers

my libssl.so is linked to libssl.so.3. Maybe try to upgrade your Ubuntu. I have the old version as well. If you can not get the new version with Ubuntu upgrade, try to install openssl with Qt installation tool. There you can install openssl 3.0.

I'm currently running 22.04. I think I must have messed this up with one of my apt installs. That's why I was asking about uninstalling the old version. Removing openssl completely appears to be rather intrusive:

he following packages will be REMOVED:
  apport apport-gtk apturl awscli bluez-cups ca-certificates cups cups-browsed
  cups-core-drivers cups-daemon gnome-control-center gnome-online-accounts

  update-manager-core update-notifier update-notifier-common xorg xserver-xorg
0 upgraded, 0 newly installed, 51 to remove and 25 not upgraded.
After this operation, 590 MB disk space will be freed.

So I don't want to do that.

[JoeCFD]

@mzimmers Understand. It is weird that you can not upgrade libssl. The latest version in 22.04 is 3.0.2.
What is the output?
apt list openssl

[mzimmers]

@JoeCFD

mzimmers@LinuxBoxZimmers:/usr/lib/x86_64-linux-gnu$ sudo apt list openssl

focal

sudo is not needed. Focal is 20.04, not 22.04. Are you sure you installed 22.04? Could be the case that libssl 1.1 points to focal.

[mzimmers]

@JoeCFD oh, would you look at that...I do have 20.04 installed. Aargh. OK, let me try to upgrade, and I'll report back.

EDIT:

22.04 installed, and the error went away. Thanks to all who looked at this.
