The problem affects Amule for Ubuntu.
I own an ubuntu 16.04, but the fix should be valid for all versions, since it affects the application and not the OS.
Alert: “An assertion failed ../src/unix/sockunix.cpp(143): assert “m_fd != INVALID_SOCKET” failed in OnReadWaiting(): invalid socket ready for reading?”
- Disconnect your computer from the internet (disable networking) before launching Amule, so that it won’t try to connect on startup.
- Open Amule preferences > connection > and unselect the check mark on “Autoconnect on startup”. Close preferences panel.
- In the Amule “Downloads” panel, pause (or stop) all downloads.
- Reconnect your computer to the net (enable networking).
- Resume your downloads.
