OpenStreetMap SSL Error

Hello,

I just installed the Skydel Software on our Server. Everything seems to work but the OpenStreetMap.

We are running an Ubuntu 20.04 Server with Skydel Version 20.9.5 (990421737) Academic License.

The moment I click on the map, the following error appears in the system terminal:

QPixmap::scaled: Pixmap is a null pixmap

With a browser on the server I can access OpenStreetMap.

Any ideas?

Hi,

Sadly, we don’t support Ubuntu 20.04 yet.

However, could you please share the versions of openssl installed on your system?
You can do so with the following command ‘ldconfig -p|grep ssl’.

Skydel map requires openssl v1.0, installing it manually with ‘apt install libssl1.0-dev’ might solve the issue.

Thank you for the info. Under Ubuntu 20.04 the command ldconfig -p | grep ssl only shows libssl.so.1.1

To just install libssl1.0-dev does not work though, because it is obsolete in Ubuntu 20.04

$ sudo apt install libssl1.0-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libssl1.0-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libssl1.0-dev' has no installation candidate

So to get libssl1.0 I had to install it from source.
Here is how I did it, maybe it helps others:

$ sudo apt install build-essential checkinstall zlib1g-dev -y
$ curl https://www.openssl.org/source/old/1.0.2/openssl-1.0.2u.tar.gz
$ tar -xf openssl-1.0.2u.tar.gz
$ cd openssl-1.0.2u
$ ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
$ sudo make
$ sudo make test
$ sudo make install
$ sudo bash -c 'echo "/usr/local/ssl/lib" > /etc/ld.so.conf.d/openssl-1.0.2u.conf'
$ ldconfig -p | grep ssl

After that the map is working so thank you a lot.

P.S.
I hope Skydel will soon support Ubuntu 20.04 officially and newer versions of OpenSSL as there are a lot of vulnerabilities in the 1.0 version.

Thank you for sharing this information with us!

We are planning on supporting Ubuntu 20.04 before the end of the year.
