Comment 12 for bug 972077

Just some rough observations, I am using a visible Proxy configures through /etc/apt/ and also HTTP_PROXY running on "http://proxy:3128/" since the early 1990ths. The Hash mismatch rarelly happened to me until I upgraded to Ubuntu 14.04 and since then I have it a lot on de.archive.ubuntu.com but still rarelly on eu/gb/nl mirrors. On most mirrors a quick fix is to clean /var/lib/apt/, /var/cache/squid and so on but on de mirror this seems to do nothing until the bug simply disappears after some days even without any interception from me.

I have the odd feeling that the de mirror is just exceptional erratic.

Why am I using a caching proxy? Because it speeds up updating and installing while using multiple clients (once had more than 100 after one 2MBit line, right now still five). There is little need to cache lists, indexes, hashes, keys and so on, I am only interested in caching the deb Files so maybe there is some workaround to ease the strain on the proxy?
