This is a repeat of my prev post which was closed automaticaly. So I force reopen it again. This time I’m gona watch answers every day to prevent closing.

I was following advice from the prev topic, but it not works for me. Below is a short result

Did you start up from the install medium in live mode?

Can you clarify plz what you mean by install medium?
Actualy I run from bootable live USB from manjaro official site. I see manjaro UI and run all this command in it’s t


erminal

Yes, that is what I meant.

Is the network up on that laptop? Can you open a browser to e.g. manjaro.org?

yes I can

And I take it you have chrooted into your Manjaro installation with manjaro-chroot?

Then issue the following command… :arrow_down:

pacman-mirrors -f 5 && pacman -Syyu

Note: That’s -Syyu, not -Syu.

yes I did exactly what you write and get this error: could not resolve host

yes i did it

Well, then it would appear that you’ve got a local network problem, and unfortunately, there isn’t anything I can do about that. :man_shrugging:

This is problem of your “could not resolve host”, because this thing configures DNS resolver, but in chrooted enviroment it’s nothing, so resolver doesn’t work. You can unlink it, create it again and pass nameserver 8.8.8.8 into it and try again.

hi Serg! thank you for replying.
can you provide set of commands for this. I’m very newbie in linux core commands🤷

OK, Alexey, here are your commands:

cd /etc
sudo rm resolv.conf
sudo cat "nameserver 8.8.8.8">resolv.conf

this should work in a chrooted enviroment, and then you will have internet, but I’m not 100% sure it works, because I didn’t test this.
