 Posted: Sat Oct 21, 2023 5:03 pm Post subject: Name server is gone after chroot [SOLVED] |
 |
|
I am following the installation guide as good as I can and experience the following problem:
When booting from the installation media, I can setup networking (wifi with dhcpd):
| Code: | livecd ~ # ping kernel.org
PING kernel.org (139.178.84.217) 56(84) bytes of data.
64 bytes from dfw.source.kernel.org (139.178.84.217): icmp_seq=1 ttl=51 time=181 ms
64 bytes from dfw.source.kernel.org (139.178.84.217): icmp_seq=2 ttl=51 time=203 ms
^C |
However, after chrooting:
| Code: | livecd ~ # chroot /mnt/gentoo /bin/bash
livecd / # source /etc/profile
export PS1="(chroot) ${PS1}" |
I get the following error when trying to emerge iw and wpa_supplicant:
| Code: | (chroot) livecd / # emerge --ask net-wireless/iw net-wireless/wpa_supplicant
...
>>> Downloading 'http://distfiles.gentoo.org/distfiles/layout.conf'
--2023-10-21 20:59:48-- http://distfiles.gentoo.org/distfiles/layout.conf
Resolving distfiles.gentoo.org... failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘distfiles.gentoo.org’
!!! Couldn't download '.layout.conf.distfiles.gentoo.org'. Aborting.

It seems that this error is due to the name server not working properly:
| Code: | (chroot) livecd / # ping kernel.org
ping: kernel.org: Temporary failure in name resolution
|
The content of /etc/resolv.conf is
| Code: | (chroot) livecd / # cat /etc/resolv.conf
# Generated by dhcpcd
# /etc/resolv.conf.head can replace this line
# /etc/resolv.conf.tail can replace this line |
I am not sure how to proceed with this situation.

That suggests you skipped the step Copy DNS info. A chroot changes the effective root (hence the name). You are now in a new root where resolv.conf is only set up if you did so personally. You need to return to the old root, copy its resolv.conf into the new root, then resume what you were doing.
Also, as a general tip, please link to documentation you are using, so that we can validate you are reading the right material. |
