Package: x2goclient-4.0.5.2-2016.09.20-setup Version: x2goclient-4.0.5.2-2016.09.20-setup Steps to reproduce: 1. Install x2goclient-4.0.5.2-2016.09.20-setup.exe 2. Make sure C:\Users\XXXXXXX\.x2go\etc does not exist, or delete it if existed. 3. Create a new session to a x2go server. 4. Enable share folder and watch the bug report window. From the source code: 9931 void ONMainWindow::startWinServers() 9932 { 9952 generateHostKey(RSA_KEY_TYPE); For Windows, we only generate RSA_KEY, but in 8013 QString ONMainWindow::createRSAKey() 8014 { 8043 #ifdef Q_OS_WIN 8044 rsa.setFileName ( 8045 wapiShortFileName ( 8046 homeDir+"\\.x2go\\etc\\ssh_host_dsa_key.pub" ) ); 8056 if ( !rsa.open ( QIODevice::ReadOnly | QIODevice::Text ) ) 8057 { We check DSA_KEY instead, which of course would not exist. To fix this bug: 8046 - homeDir+"\\.x2go\\etc\\ssh_host_dsa_key.pub" ) ); 8046 + homeDir+"\\.x2go\\etc\\ssh_host_rsa_key.pub" ) );
