New install Linksys E5600

[pepa65]

Installed the factory package on the E5600 and got as far as the ssh (nothing at port 80/443). After bringing up the network through uci I tried to get Luci. So I did opkg update and then opkg install luci.
No web page.
So opkg install luci-ssl and then /etc/init.d/uhttpd restart
Which outputted:

What is the best way to start again (or get this to work)?

Somehow I have these 2 files:
/usr/lib/libwolfssl.so.4.8.1.ba20a816 (missing symbols) and:
/usr/lib/libwolfssl.so.4.8.1.39c36f2f (but this one isn't used).
How can I get rid of the former and get the system to use the latter?

OK, what I didn't realize that I needed to install the factory image, and then upgrade it. I did a soft-factory reset with:
firstboot -y && reboot now

And then setup the internet through ssh as in:

Use SSH to connect to the internet and install LuCI web interface

Then I downloaded the sysupgrade image and installed that:

cd /tmp
wget http://downloads.openwrt.org/snapshots/targets/ramips/mt7621/openwrt-ramips-mt7621-linksys_e5600-squashfs-sysupgrade.bin
sysupgrade openwrt-ramips-mt7621-linksys_e5600-squashfs-sysupgrade.bin

Now when I did opkg update and installed luci and luci-ssl it worked, and the GUI got served!
