Raspberry Pi not updating via rpi-update - Raspberry Pi Forums

hello, have rpi 1 model b on installed raspbian , moved installation external hdd using guide: viewtopic.php?f=29&t=44177

time ago noticed problems openvpn service, cannot start properly:

code: select all

root@raspberrypi:/home/pi# service openvpn start [....] starting virtual private network daemon: serversiocsifaddr: no such device : error while getting interface flags: no such device siocsifdstaddr: no such device : error while getting interface flags: no such device siocsifmtu: no such device failed!

tracked problem down fact there no appropriate modules (tun in case) kernel (how did end in state?)

code: select all

root@raspberrypi:/home/pi# uname -a linux raspberrypi 3.18.7+ #755 preempt thu feb 12 17:14:31 gmt 2015 armv6l gnu/linux root@raspberrypi:/home/pi# cd /dev/net root@raspberrypi:/dev/net# ls tun root@raspberrypi:/dev/net# ls -l total 0 crw-rw-rwt 1 root root 10, 200 jan 1 1970 tun root@raspberrypi:/dev/net# modinfo tun libkmod: error ../libkmod/libkmod.c:554 kmod_search_moddep: not open moddep file '/lib/modules/3.18.7+/modules.dep.bin' error: module alias tun not found. root@raspberrypi:/dev/net# cd /lib/modules/ root@raspberrypi:/lib/modules# ls -a . .. 4.1.7+ 4.1.7-v7+ 

@ point tried updating, starting apt-get update, apt-get upgrade, apt-get dist-upgrade ran fine, without updating kernel or modules.

tried running rpi-update, downloaded new version of kernel, after reboot (and puzzles me bit) version uname -a reports it's still: linux raspberrypi 3.18.7+ #755 preempt thu feb 12 17:14:31 gmt 2015 armv6l gnu/linux.

@ point remembered installed raspbian on sd card , moved external hdd, /boot partition (again i'm bit puzzled) not in output of df -h:

code: select all

root@raspberrypi:/home/pi# df -h filesystem      size  used avail use% mounted on rootfs          459g  8.9g  427g   3% / /dev/root       459g  8.9g  427g   3% / devtmpfs         87m     0   87m   0% /dev tmpfs            19m  212k   18m   2% /run tmpfs           5.0m     0  5.0m   0% /run/lock tmpfs            37m     0   37m   0% /run/shm 

/etc/fstab tells me /boot should there:

code: select all

root@raspberrypi:/home/pi# cat /etc/fstab proc            /proc           proc    defaults          0       0 /dev/mmcblk0p1  /boot           vfat    defaults          0       2 /dev/sda1       /               ext4    defaults,noatime  0       1 # swapfile not swap partition, no using swapon|off here on, use  dphys-swapfile swap[on|off]  

sd card firmly inserted in slot:

code: select all

root@raspberrypi:/home/pi# lsblk name        maj:min rm   size ro type mountpoint sda           8:0    0 465.8g  0 disk  └─sda1        8:1    0 465.8g  0 part / mmcblk0     179:0    0   7.3g  0 disk  ├─mmcblk0p1 179:1    0    56m  0 part  └─mmcblk0p2 179:2    0   2.7g  0 part  

how fix mess here?
i'd able to:

• figure out why on earth there's no /boot partition sd card though sd recognized , listed in fstab
  upgrade pi
  start openvpn

are there files in /boot directory? guess, sounds copied on sda, including /boot, can't used mount point. if so, move in /boot temp directory, make sure /boot empty, mount /dev/mmcblk0p1. can re-run rpi-update.
