I am currently trying to install iperf3 package on my RUTM52. However, I have encountered that after running the opkg install iperf3 command, the response was Unknown package ‘iperf3’ Package installation encountered an error, removing previously installed package, so I decided to follow the commands indicated in the following issue:
Nonetheless, after running the first command opkg -e /etc/opkg/openwrt/distfeeds.conf update, I get the following downloading error, and it does not allow me to download iperf3 package — obviously.
Of course, the test was run on a RUTX11 instead of an M52, and the firmware in use was 7.17.5, but this generally shouldn’t make much of a difference.
Could you please confirm that if running these commands in this particular order still returns the error? opkg update opkg install iperf3
Could you also confirm your current firmware version installed on the device? If not at least 7.17.5, could you kindly upgrade to it? Downloads can be found here: RUTM52 Firmware Downloads - Teltonika Networks Wiki
Thanks for getting back to me so quickly! The current firmware version installed on my RUTM52 is 7.15.5, the same as yours. I am not sure what happened over the past few days while I was not working with it, but I have just run the commands you suggested, and the error did not appear (just like in Konrad’s case).
