lostirc 0.4.6-4.3 (riscv64 binary) in ubuntu kinetic

 LostIRC is a simple, yet very useful IRC-client. It has features such as
 tab-autocompletion, multiple server support, automatic joining of
 servers/channels and DCC sending which should cover the needs of most
 people. The client is 100% keyboard-controllable, and uses the gtkmm
 GUI library.
