I'm running SNAPSHOT r8689-5beedcd and installed Luci afterwards. Because I hate the anoying warnings I followed https://openwrt.org/docs/guide-user/luci/getting-rid-of-luci-https-certificate-warnings afterwards I found myself locked out of Luci.
I'll get the following error after aplying the last step.
root@OpenWrt:/etc/ssl# /etc/init.d/uhttpd restart
4+0 records in
4+0 records out
Generating a 2048 bit RSA private key

mv: can't rename ' /etc/ssl/mycert.key.new': No such file or directory
mv: can't rename ' /etc/ssl/mycert.crt.new': No such file or directory
I still have access via putty so I hope somebody can help me to put this right.
