The KEK electron/positron injector linac was upgraded for Phase-II SuperKEKB (HER/LER). Pulsed magnets were installed in the linac for simultaneous injection to four different rings, HER/LER/PF/PF-AR. RF gun improvement for stable high-charged beam generation was also done. Phase II commissioning have already started in March 2018. For Phase III commissioning, more stable high-quality beam operation is necessary. This report describes the present status of the linac and the related upgrade efforts for Phase III.
