Permission denied (public key) when running ./update with git on Nios2 Linux

[Altera_Forum]

hi, I am using Centos 6.4 on 64 bits OS and I follow the instruction at http://www.alterawiki.com/wiki/install_nios_ii_linux, I got the following error when running [/home/hippo/nios2-linux]# ./update 

update binutils.. Already up-to-date. update gcc3.. Already up-to-date. update linux-2.6.. Already up-to-date. update toolchain-build.. Already up-to-date. update toolchain-mmu.. Already up-to-date. update uClibc.. Already up-to-date. update elf2flt.. Already up-to-date. update insight.. Already up-to-date. update u-boot.. Already up-to-date. update uClinux-dist.. Already up-to-date. update boards.. Already up-to-date. update openip.. Permission denied (publickey). fatal: The remote end hung up unexpectedly update tools.. Your configuration specifies to merge with the ref 'master' from the remote, but no such ref was fetched.  May I know how can I get over this? Is it necessary for openip and tools to get update?

 git clone git://sopc.et.ntust.edu.tw/git/boards.git git clone git://sopc.et.ntust.edu.tw/git/openip.git git clone git://sopc.et.ntust.edu.tw/git/tools.git
