    <p>OpenWRT version 23.05.0-rc3 is, for starters, not supported
      anymore by the OpenWRT project, and is old.</p>
    <p>The current version is OpenWRT 23.05.05</p>
    <p>The reason you are likely getting an old version of NUT when you
      load the nut package is because you are using an old version of
      openwrt.</p>
    <p>Your team needs to sysupdate your 4G LTE Wifi router</p>
    <p>You also, in my opinion, need to seriously reconsider running NUT
      on an openwrt router.  The reason why is that NUT generates
      logfiles and writes to the filesystem.</p>
    <p>The flash chips that are used on routers are not designed like a
      USB flash stick where they are intended to have a read/write
      filesystem on them.  They have no bad block management with NAND
      flash chips.  That is provided by a UBI layer.  You can read about
      that here:</p>
    <p><a href="https://openwrt.org/docs/techref/flash.layout">[OpenWrt
        Wiki] The OpenWrt Flash Layout</a></p>
    <p>SOME of the NAND devices that OpenWRT has been ported to, DO have
      complete UBI support, others don't.  You did not say what model of
      router you are running - but unless you have researched it and are
      completely sure that it has a fully functional bad block
      management, you can easily cause problems over time attempting to
      run programs on an OpenWRT router.</p>
    <p>In general it's safest to run READ ONLY programs on openwrt.  For
      example, the snmpd server.  Programs that WRITE to the filesystem
      on the OpenWRT router should be avoided.</p>
    <p>There's a reason we use hard drives on servers.</p>
