Some ISPs intercept their clients' downloads. The error is telling you
that the download appears to have been modified in transit, so isn't
safe to install. It cannot tell you why or where that happened,
unfortunately.

This bug was to track a known case of an index file appearing to have
been modified in transit due to a known race condition. That issue was
fixed, and it seems unlikely to me that you are affected by that
particular issue as your mismatch is on deb and not an index file.

If you need help, you're more likely to get it from a place dedicated to
that, since few people follow this particular bug. See
