Hello,  
I’m trying to install ipref3 tool on my RUTX50 RUTX\_R\_00.07.06.3.  
I run the commands:

- opkg update
- opkg install iperf3  
As a response I get Unknown package ‘iperf3’  
Does anyone know what am I doing wrong?

Best Regards,  
Konrad

Thanks. After running 1st command “opkg -e /etc/opkg/openwrt/distfeeds.conf update” I get downloading error:  
"Downloading [https://downloads.openwrt.org/releases/21.02.0/packages/arm\_cortex-a7\_neon-vfpv4/vuci/Packages.gz](https://downloads.openwrt.org/releases/21.02.0/packages/arm_cortex-a7_neon-vfpv4/vuci/Packages.gz)  
\*\*\* Failed to download the package list from [https://downloads.openwrt.org/releases/21.02.0/packages/arm\_cortex-a7\_neon-vfpv4/vuci/Packages.gz](https://downloads.openwrt.org/releases/21.02.0/packages/arm_cortex-a7_neon-vfpv4/vuci/Packages.gz)  
Collected errors:

Then:  
“root@RUTX50:~# opkg -e /etc/opkg/openwrt/distfeeds.conf list | grep iperf3  
iperf3 - 3.10.1-1 - Iperf is a modern alternative for measuring TCP and UDP bandwidth performance, allowing the tuning of various parameters and characteristics.  
iperf3-ssl - 3.10.1-1 - Internet Protocol bandwidth measuring tool with iperf\_auth support”

But finally instalation doesn’t work:  
“root@RUTX50:~# # opkg -e /etc/opkg/openwrt/distfeeds.conf install iperf3  
root@RUTX50:~# opkg install iperf3  
Unknown package ‘iperf3’.”

Hi,

I tested the issue myself and couldn’t recreate it. Could you please share the command line output after executing these commands:

```auto
opkg -e /etc/opkg/openwrt/distfeeds.conf update

```

and

```auto
opkg -e /etc/opkg/openwrt/distfeeds.conf install iperf3

```

Regards,

Marijus
