hmm, do you have enough free space to decompress it? The logic to determine whether a file is corrupted may be something along the lines of: try to decompress, if there's a failure (no matter if that's caused by no more disk space) then report that it's corrupt. How can dpkg -i install it? You're talking about on the tablet I presume? CORRECT I thought that the whole file had to be decompressed before the bits are moved around or is dpkg more intelligent than that and can decompress individual parts somehow?
