Okay, well in my case I got rootsh installed...using Healthcheck app it says I'v got 31.4MB left on roofs but still cant install d 16MB update or anything else for that matter,neither can I uninstall any app whatsoever! I spent d whole of ystdy reading thru all 223 posts on this thread and now I'm more confused than I initially was. I wld love to get rid of all d apps I got from extra devel via xterm as my App manager has been rendered totally useless, hoping that wld solve d problem...having disabled extra-devel repository,closed App manager these are d steps I'v taken with d results I got:
"rm /var/lib/apt/lists/*" to remove the repository metadata to give me enough free space to uninstall and I got rm : /var/lib/apt/lists/partial is a directory

apt-get remove qtirecco (since I suspect qtirreco is a culprit)
result
E: could not open lock file var/cache/apt/archives/lock - open (2 no such file or directory
E: Unable to lock the download directory


a little detailed help please for this noob please...I dont wanna flash my device as I fear I might just take a wrong turn and mess d device all up...just like I did to my iphone...please help!
