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: - opkg\_download: Failed to download h{only\_2\_links\_in\_post}ttps://downloads.openwrt.org/releases/21.02.0/packages/arm\_cortex-a7\_neon-vfpv4/vuci/Packages.=.gz, wget returned 8."
