I couldn't install luci-app-transmission - git-17.119.62808-1497d4a-1 ... wen't to investigate, and found that other packages were affected. When I did the opkg install for transmission, this came up:
Error printed out is.
uci: Parse error (invalid command) at line 1, byte 0
uci: Entry not found
uci: Parse error (invalid command) at line 1, byte 0
Debugged the opkg output and what fails is when running /usr/lib/opkg/info/luci-app-transmission.postinst ... went there and found the file, and also a file called luci-app-transmission.postinst**-pkg**
Last time I found a similar issue, there was a typo in one of my "/etc/config" files: opkg calls uci during some installations, and uci reviews all config files each time; if there is a typo in your config files, opkg will fail (even if the typo is irrelevant to the packages being installed).
Execute "uci changes" and see if it reports any error.
I've found that it was throwing several errors because I've placed weird files in the /etc/config directory. I've moved them out, and now uci changes is just reporting one line with an error:
uci: Parse error (invalid command) at line 1, byte 0
FIXED IT!!! I had also a script in the /etc/config folder... just removed it and now UCI Changes is not reporting any errors,a nd I was able to install the packages. Thanks for the tip!
