Coba lagi. Error seperti ini terjadi ketika ada repo yang sedang dalam proses update dan diwaktu yang sama anda lakukan proses install.

[masfebriyan]

sudah saya coba berkali kali seprti itu terus pak, saya instal ulang centos masih ttp sama pak

[MRatWork]

Coba jalankan dulu 'yum clean all' sebanyak 3-4 kalu sebelum 'yum update -y'.

[masfebriyan]

begini tapi hasil y masih sama pak,,

Coba ubah di bagian '[mratwork-epel]' dari '#baseurl=' ke 'baseurl=' dan 'mirrorlist' ke '#mirrorlist'. Kemudian jalankan 'yum clean all; yum update -y'.
