I Have to Change between networks to download packages using pacman

whiskyburger · 2020-09-15 06:16:19

Hello everyone

I have and odd issue, i can't use pacman in a normal way even if i use Ethernet cable or the WiFi network (the same router that has the cable) pacman don't let me download anything, but i can use firefox!!, the only way i can download packages is changing to another WiFi network, like to my cellphone WiFi network. This is really odd, i didn't find anything in the internet.
PD: I tried other distros before and this is the first time this happened to me
PD2: to install arch i used iwctl at the beginning of the installation to connect to my cellphone WiFi network

The Mirrors that i use are base-calculated with reflector -sort rate

i leave this example here.

Thank you in advance for read.

error: failed retrieving file 'core.db' from mirrors.udenar.edu.co : Resolving timed out

Could this be a name server issue?

cat /etc/resolv.conf
drill mirrors.udenar.edu.co

If you are using router as a DNS forwarder, pls check it's configuration. even if you disable host file /etc/resolv.conf firefox/chrome/ping will still work. "drill" on the otherhand relay on /etc/resolv.conf as default resolver.

i'm not sure if my router is setup as DNS fowarder but i'll check the configuration tomorrow.

this are the results using those commands

[@arch etc]$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.0.1
options single-request
[@arch etc]$ drill mirrors.udenar.edu.co
bash: drill: command not found
[@arch etc]$

i already tried to install ldns to run drill but this message appears. (i'm using my cellphone wifi network, not my home wifi network or ethernet cable)

[@arch etc]$ sudo pacman -S ldns

Please upload /etc/pacman.d/hooks/mirrorupgrade.hook (eg. first link in my signature)

Your networkmanager indeed configured to use your router 192.168.0.1 as dns resolver. First, reconfigure your networkmanager to use 8.8.8.8 or 1.1.1.1 and then test again with:

Allways sync database before install new package.
# pacman -Syy
# pacman -S ldns
$ drill archlinux.org

Great, you fixed it! I guess your next mission is to figuring out way your router couldn't resolv your dns request. good luck!

seth · 2020-09-19 06:22:13

1. It should be "Operation = Upgrade" (that's causing the error)
2. Assuming 192.168.0.1 is your router you should rather fix the DNS configuration there. "nmap -p 53 192.168.0.1" to see whether the IP has a DNS server at all.

Also cross check the output of "ip a" on whether (in the failing case) you're in a different subnet than 192.168.0.0/24 and if so, which.
Then fix the NM configuration accordingly, based on whether there's a local DNS server in the other subnet.

If there's no subnet differences and you can "ping 192.168.0.1" under all circumstances and "nmap -p 53 192.168.0.1" is also open under all circumstances, you'll have to inspect the router configuration and maybe provide fallback mechanisms for a wonky ISP DNS (but from the problem description, that's actually less likely)
