Hello Guix,

executive summary: this bug is still to be triaged since I've
succesfully used the same steps some days ago, so it could be a false
positive



I'm having a strange error when installing Guix 1.0.0 from USB media
using the Newt Graphical Install

Recently I succesfully installed using the same steps (newt installer)
and the network was succesfully detected, but now I got this message
twice [1]:

=2D-8<---------------cut here---------------start------------->8---

  ...requires internet access but no network device were found

=2D-8<---------------cut here---------------end--------------->8---

Switching to a terminal console I was able to:

1. check the eno1 interface was correctly detected (via "ip a ls")
2. start the interface (ifconfig eno1 up)
3. get an IP via DHCP client (dhclient -v eno1)
4. ping gnu.org

Sorry but I don't know how to debug the installer or find a specific log
file from it to help better understand why the installer does not find
the network device

Following /var/log/debug on a console I see no error messages right
before the above mentioned message appears in installer, even selecting
"Continue" or exiting the next dialog and re-selecting=20

After eno1 "manual" setup I was able to complete the install

As I already mentioned, some day ago I'm *sure* the installer correctly
detected and activated the network interface (using another USB pen
drive) and I really don't understand what changed here :-O

The one and only test that comes to my mind is to double check the
content wrote to the pen drive is not somehow corrupted, I got it and
dd'ed following the Guix manual instructions [2]

I'll check and/or redo my install media to see if that's the problem

If you have any other hint or "debug trick" please comment

Thanks! Gio'

I hope this is an instance of <https://issues.guix.info/issue/35550>,
that is “herd status wpa-supplicant” shows that wpa-supplicant is
stopped instead of running?  I hope there will be a new release soon
where this is fixed.

Florian

Hello Guix,

actually I had a faulty USB media (details below): I've redone it but
nothing changed, I'm still getting the "Internet access" dialog with an
error message telling "no network device were found"

=2D-8<---------------cut here---------------start------------->8---
$ sudo cmp -n `stat -c '%s' guix-system-install-1.0.0.x86_64-linux.iso` gui=
x-system-install-1.0.0.x86_64-linux.iso /dev/sdb
guix-system-install-1.0.0.x86_64-linux.iso /dev/sdb differ: byte 4128769, l=
ine 1274
=2D-8<---------------cut here---------------end--------------->8---

so I computed the sha1sum of the downloades ISO image:

=2D-8<---------------cut here---------------start------------->8---
$ sha1sum guix-system-install-1.0.0.x86_64-linux.iso
724eaa8f6f80ed65d07965f2b96282023c6736c3  guix-system-install-1.0.0.x86_64-=
linux.iso
=2D-8<---------------cut here---------------end--------------->8---

and the one from my pen drive:

=2D-8<---------------cut here---------------start------------->8---
$ sudo head -c $(stat -c '%s' guix-system-install-1.0.0.x86_64-linux.iso) /=
dev/sdb | sha1sum=20
9ad81a175d49df62561bb274cc74bafb7a9cc199  -
=2D-8<---------------cut here---------------end--------------->8---

they differ: the USB pen drive image was corrupted!

now I remember: I'm almost sure I did not _sync_ the device after dd, as
clearly stated in the documentation

I copied the ISO again (dd if=3Dguix-system-install-1.0.0.system.iso
of=3D/dev/sdX && sync) and re-computed the USB pen drive sha1sum:

=2D-8<---------------cut here---------------start------------->8---
$ time sudo head -c $(stat -c '%s' guix-system-install-1.0.0.x86_64-linux.i=
so) /dev/sdb | sha1sum=20
724eaa8f6f80ed65d07965f2b96282023c6736c3  -
=2D-8<---------------cut here---------------end--------------->8---

it corresponds to the ISO one now

really strange...

HTH! Gio'

Hi Florian,

thank you for pointing me to the right bug report!

I checked the bug reports list via web [1] but did not link
wpa-supplicant to my issue since I did not realized that such an issue
also affects wired connections

"pelzflorian (Florian Pelz)" <pelzflorian@HIDDEN> writes:

> I hope this is an instance of <https://issues.guix.info/issue/35550>,

yes, this is definitely an instance of #35550

I confirm I see the very same wpa_supplicant log messages in
/var/log/messages as reported by Sirgazil and pelzflorian

the following suggested workaround (in a text console activated via
CTRL-ALT-F3) works for me:

=2D-8<---------------cut here---------------start------------->8---
pkill wpa_supplicant
herd start networking
=2D-8<---------------cut here---------------end--------------->8---

after that I was able to restart the "Network interface" installer step
(by choosing "Exit" and selecting it again in the proposed dialog) and
was able to select the wired interface

Thanks! Gio'
