Uci errors during opkg update

Hi guys,
I keep getting these errors during opkg update for some packages:

"uci: Parse error (invalid command) at line 34, byte 0"

Configuring luci-lib-nixio.
Configuring luci-lib-ip.
Configuring luci-lib-jsonc.
Configuring luci-base.
Configuring luci-compat.
Configuring luci-lib-iptparser.

Collected errors:
 * resolve_conffiles: Existing conffile /etc/config/adblock is different from the conffile in the new package. The new conffile will be placed at /etc/config/adblock-opkg.
 * resolve_conffiles: Existing conffile /etc/config/luci is different from the conffile in the new package. The new conffile will be placed at /etc/config/luci-opkg.
 * resolve_conffiles: Existing conffile /etc/config/ucitrack is different from the conffile in the new package. The new conffile will be placed at /etc/config/ucitrack-opkg.

Are these parsing errors due to the diff between the config files?

Thanks.

If I remember correctly, that is an indication of errors in your config files.
