Linux AppImage LeoCAD-Linux-21.06-x86_64.AppImage has a strange error about "connecting" to update server

[yngmjgsd]

Describe the bug
Cannot connect to update server on Linux (Kubuntu 22.04 was tested)

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Help' menu
2. Click on 'Check for Updates...'
3. See error "Error connecting to the update server."

Expected behavior
Must show successful results cause the application compiled from the source (using QtCreator and Qt 5.15.2) works just fine on the same system which doesn't explain what is wrong with the source code, or system configuration.

Screenshots
This is how it looks.

Version (please complete the following information):

• OS: Kubuntu 22.04
• LeoCAD Version 21.06, from LeoCAD-Linux-21.06-x86_64.AppImage file

Crash information:
No crash.

The actual question is - is there any specifics for AppImage 21.06 here? The version compiled from sources works just fine.

This might be related to one of AppImage issues with bundled/missed SSL lib:

• [SOLVED] Error running AppImage: still openssl problem AppImage/AppImageKit#998

Here is actual latest LeoCAD-Linux-8eec5756-x86_64.AppImage terminal output:

$ ./LeoCAD-Linux-8eec5756-x86_64.AppImage
qt.network.ssl: QSslSocket: cannot resolve EVP_PKEY_base_id
qt.network.ssl: QSslSocket: cannot resolve SSL_get_peer_certificate
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_get_peer_certificate

Issue still is actual for latest build:

$ ./LeoCAD-Linux-da803dc3-x86_64.AppImage
qt.network.ssl: QSslSocket: cannot resolve EVP_PKEY_base_id
qt.network.ssl: QSslSocket: cannot resolve SSL_get_peer_certificate
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_get_peer_certificate

@leozide, may ask You to take a look on adding new option for import inventory from downloaded files in BrickLink XML and/or Rebrickable CSV formats? (in offline)

• Import set inventory from file (in offline) #774

Note, there is old AppImage topic with (old?) solution, I'm not sure is it already implemented in LeoCAD or not, but I would leave solution patch here too:

• https://www.github.com/AppImage/AppImageKit/issues/998#issuecomment-543368166

# copy some missed libs to the bundle
cp $(ldconfig -p | grep libssl.so.1 | head -n1 | tr ' ' '\n' | grep /) ./$APP.AppDir/Qt/libs/
cp $(ldconfig -p | grep libcrypto.so.1 | head -n1 | tr ' ' '\n' | grep /) ./$APP.AppDir/Qt/libs/
cp $(ldconfig -p | grep libicui18n.so | head -n1 | tr ' ' '\n' | grep /) ./$APP.AppDir/Qt/libs/
cp $(ldconfig -p | grep libicuuc.so | head -n1 | tr ' ' '\n' | grep /) ./$APP.AppDir/Qt/libs/
cp $(ldconfig -p | grep libicudata.so | head -n1 | tr ' ' '\n' | grep /) ./$APP.AppDir/Qt/libs/

# run linuxdeploy and generate an AppDir
export APPIMAGE_EXTRACT_AND_RUN=1
./linuxdeploy-x86_64.AppImage --appdir ./$APP.AppDir --output appimage

Anothe workaround is if there is a version mismatch, try to patch Qt Networking lib binary (this could be done on-the-fly with Actions CI YAML)

Just wanted to drop a note about Qt 5.10.1:

use sed -i -e 's|1.0.2k|1.0.0\x00|g' /path/to/myappimg/usr/lib/libQt5Network.so.5

because it changed with the latest Qt SDK:

$ strings libQt5Network.so.5 | grep '1\.0\'.
1.0.2k
OpenSSL version too old, need at least v1.0.2
