package chromium-browser (not installed) failed to install/upgrade: cannot copy extracted data for './usr/lib/chromium-browser/libs/libblink_web.so' to '/usr/lib/chromium-browser/libs/libblink_web.so.dpkg-new': unexpected end of file or stream

I continually get hash sum mismatch errors when downloading chromium-browser through apt-get.
I held shift while clicking the link to the file and downloaded it.
I used kdesudo dolphin to open up dolphin file browser and copied the chromium-browser.deb file into
/var/cache/apt/partial folder, and ran it from there.

[Ubuntu Foundations Team Bug Bot (crichton)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error on your system when trying to install a particular package. Please execute the following command, as it will clear your package cache, in a terminal:

sudo apt-get clean

Then try performing the update again. This will likely resolve your issue, but the failure could be caused by filesystem or memory corruption. So please also run a fsck on your filesystem(s) and a memory test. Thanks in advance!
