Mele A100 : how to update system / disable IPV6

[brno]

Hi,
I installed Archlinux on my Mele, following the procedure (http://archlinuxarm.org/platforms/armv7 ... /mele-a100).
The problem is that when I try to use pacman, I have messages like this one: "error: failed retrieving file 'core.db' from mirror.archlinuxarm.org : Could not resolve host: mirror.archlinuxarm.org"
If I understand, this problem is related to the ipv6 module, that runs by default in Archlinux (but I'm not sure that it is the real problem).
I tried to disable it unsuccessfully, using many ways.... and as I'm quite a newbie in Archlinux (and Linux), I don't know what to do now. I would be grateful if you can help me !

Perhaps edit /boot/uEnv.txt to look like this
$this->bbcode_second_pass_code('', 'extraargs=rootwait disable.ipv6=1')

Thanks! I just tried it, and unfortunately the problem remains the same

When I execute "pacman -Syu", I have the following error:
$this->bbcode_second_pass_code('', ':: Synchronizing package databases...

')

the answer to the command "cat /proc/sys/net/ipv6/conf/all/disable_ipv6" is "0", and I don't know if that's normal...

In which case, as per https://wiki.archlinux.org/index.php/Systemd#Temporary_files
$this->bbcode_second_pass_code('', 'echo "w /proc/sys/net/ipv6/conf/all/disable_ipv6 - - - - 1" >/etc/tmpfiles.d/disable-ipv6.conf')

The error stay the same.

$this->bbcode_second_pass_code('', 'error: failed retrieving file 'core.db' from mirror.archlinuxarm.org : Could not resolve host: mirror.archlinuxarm.org
')

And the answer to the command "cat /proc/sys/net/ipv6/conf/all/disable_ipv6" is still "0"

Don't know what to do Maybe I have to configure the network on the Mele ? At this time, it is in DHCP...

Following this thread (viewtopic.php?f=31&t=5743&start=30), I tried
pacman -Scc > done
pacman -Syy > same error (error: failed retrieving file 'core.db' from mirror.archlinuxarm.org : Could not resolve host: mirror.archlinuxarm.org)

Seems that ipv6 is already disabled... When I open "/etc/hosts", I already see this line :
$this->bbcode_second_pass_code('', '::1 localhost.localdomain localhost')
Maybe ipV6 is not the source of the problem ?
