Hi Will,
I have booted fc19 as per
http://fedoraproject.org/wiki/Architectures/ARM/AArch64/QuickStart
successfully and able to setup networking.
However, when I tried to install basic packages like git, it throws
timeout errors:
----------------------------
[root@localhost ~]# yum install git-core
Loaded plugins: langpacks, refresh-packagekit
arm64 | 2.9 kB 00:00
http://arm-temp.ausil.us/pub/fedora-arm/stage4/repodata/repomd.xml:
[Errno 12] Timeout on
http://arm-temp.ausil.us/pub/fedora-arm/stage4/repodata/repomd.xml:
(28, 'Connection timed out after 30050 milliseconds')
Trying other mirror.
----------------------------
What could be the issue? Is it could be because of slow internet or I
am missing something?
Thanks,
Sandeepa
