Problem:
When running opkg update or other opkg commands in OpenWRT, you see these error messages:
Failed to send request: Operation not permitted
Full log example:

Solution:
This problem is typically caused by no DNS servers being set.
First, check if you have internet access using
ping 1.1.1.1
The output should look like this (otherwise, you have no internet access):
root@OpenWrt:~# ping 1.1.1.1 PING 1.1.1.1 (1.1.1.1): 56 data bytes 64 bytes from 1.1.1.1: seq=0 ttl=59 time=36.078 ms 64 bytes from 1.1.1.1: seq=1 ttl=59 time=33.538 ms 64 bytes from 1.1.1.1: seq=2 ttl=59 time=33.350 ms
Now try to ping techoverflow.net:
root@OpenWrt:~# ping techoverflow.net ping: bad address 'techoverflow.net'
This verifies that you have internet connectivity but no DNS.
Now go into LuCI, go to Network/Interfaces and edit each interface. Set
1.1.1.1
and
1.0.0.1
This might not be possible for some interfaces since they have a different IP address configuraton (in that case, just proceed with the other interfaces). The configuration for the interface should now look like this:
Don’t forget to Save & Apply!
After that, retry opkg update which should now look like this:
root@OpenWrt:~# opkg update Downloading http://downloads.openwrt.org/releases/19.07.5/targets/ath79/generic/packages/Packages.gz Updated list of available packages in /var/opkg-lists/openwrt_core Downloading http://downloads.openwrt.org/releases/19.07.5/targets/ath79/generic/packages/Packages.sig Signature check passed.
