Just run the opkg update command to ensure the package list is up to date. It is also not recommended to frequently update the system’s default software unless there are noticeable performance issues.To use these mirror sources, you need to modify the OPKG software source on the OpenWRT router. You can check the /etc/opkg/customfeeds.conf file to ensure it is correctly configured according to the OpenWRT version and device architecture you are using.OPKG configuration example:src/gz openwrt_core https://mirror.bjtu.edu.cn/openwrt/releases/<version>/targets/<target>/packagessrc/gz openwrt_base https://mirror.bjtu.edu.cn/openwrt/releases/<version>/packages/<architecture>/basesrc/gz openwrt_luci https://mirror.bjtu.edu.cn/openwrt/releases/<version>/packages/<architecture>/lucisrc/gz openwrt_packages https://mirror.bjtu.edu.cn/openwrt/releases/<version>/packages/<architecture>/packagessrc/gz openwrt_routing https://mirror.bjtu.edu.cn/openwrt/releases/<version>/packages/<architecture>/routingsrc/gz openwrt_telephony https://mirror.bjtu.edu.cn/openwrt/releases/<version>/packages/<architecture>/telephonyShellCopyReplace https://mirror.bjtu.edu.cn/openwrt/ in the above content with the OpenWRT software source address you want to use, and note that the <version> is the version number that needs to be modified to your OpenWRT version, and <architecture> is the system architecture that needs to be modified to your corresponding system architecture, such as X86_64.Common OpenWRT architectures:You can check the system architecture using the following code; the table contains commonly used architectures.# Check the current CPU architectureuname -m# Check the acceptable CPU architectures for the systemopkg print-architecturePlain textCopyInstruction setArchitecture / Sub-architectureOpenWrt package structureㅤarm64/genericlayerscape/64baarch64_armv8-aㅤarc770/genericarc_arc700ㅤarchs38/genericarc_archsARMbrcm2708/bcm2708arm_arm1176jzf-s_vfpARMat91/legacymcs814x/genericmxs/genericarm_arm926ej-sARMipq806x/genericarm_cortex-a15_neon-vfpv4ARMat91/sama5d3arm_cortex-a5ARMbrcm2708/bcm2710arm_cortex-a53_neon-vfpv4ARMmediatek/genericarm_cortex-a7ARMbrcm2708/bcm2709arm_cortex-a7_neon-vfpv4ARMsunxi/genericarm_cortex-a8_vfpv3ARMbcm53xx/genericlayerscape/32barm_cortex-a9ARMimx6/genericzynq/genericarm_cortex-a9_neonARMmvebu/genericomap/genericarm_cortex-a9_vfpv3ARMgemini/raidsonicgemini/wiligeararm_fa526ARMoxnas/genericarm_mpcoreARMcns3xxx/genericarm_mpcore_vfpARMkirkwood/genericarm_xscaleARMixp4xx/genericixp4xx/harddiskarmeb_xscaleMIPS64malta/be64mips64_mips64MIPS64octeon/genericmips64_octeonMIPS64malta/le64mips64el_mips64MIPSar71xx/genericar71xx/nandar71xx/mikrotiklantiq/xrx200lantiq/xwaylantiq/xway_legacymalta/bemips_24kcMIPSadm5120/router_beath25/genericbrcm63xx/genericbrcm63xx/smpmips_mips32MIPSmalta/leramips/rt305xramips/mt7620ramips/mt7621ramips/mt7628ramips/mt7688mipsel_24kcMIPSbrcm47xx/mips74kramips/rt3883mipsel_74kcMIPSadm5120/router_leadm5120/rb1xxadm8668/genericar7/genericar7/ac49xau1000/au1500au1000/au1550brcm47xx/genericbrcm47xx/legacyrb532/genericxburst/qi_lb60mipsel_mips32MIPSramips/rt288xmipsel_mips32r2PPCppc44x/genericpowerpc_440PPCapm821xx/nandapm821xx/satapowerpc_464fpPPCmpc85xx/generic, mpc85xx/p1020powerpc_8540x86x86/geodei386_geodex86x86/legacyi386_i486x86x86/generici386_pentium4x86_64x86/64x86_64Command line to replace OPKG software source:Or modify via command line, format: s,[original software source address],[replacement software source address],gsed -e ‘s,https://downloads.openwrt.org,https://mirror.bjtu.edu.cn/openwrt,g’ \-e ‘s,https://downloads.openwrt.org,https://mirror.bjtu.edu.cn/openwrt,g’ \-i.bak /etc/opkg/customfeeds.confPlain textCopyAfter replacement, update using opkg update.Notes:The official OpenWRT software source may not fully match third-party firmware such as those customized by esir, Leon, etc., which may have incomplete libraries or compatibility issues. Additionally, the k-mod-*.ipk software packages provided by the official version may also have installation issues.If you are a beginner or just want to set up the OpenWRT system for basic use, it is recommended to use ImmortalWRT, which may have better support for software sources and allows for custom configuration of domestic software sources with immoralwrt-opkg-replace-edu-mirror.In the latest snapshot version, OpenWRT has replaced opkg with the apk package manager, so be cautious about version compatibility when changing software sources. It is not recommended for beginners or novices to use snapshot (SNAPSHOT) or RC versions, nor to use non-open-source third-party firmware.
