https://forum.armbian.com/search/?q=Hash Sum mismatch&quick=1 We need to extend repository index synchronisation timeout from 1 day to several days since mirrors doesn't get in sync in this time frame. The problem is that current main rsync server is slow (only 50Mbps upload in total), but is cheap and has no traffic limits. We know how to solve this, but we lack time: https://armbian.atlassian.net/browse/AR-789

OK, trying from scratch: 1.

Cannot figure out what the problem is. The "solution nr. 1" fro google, rm -rf /var/cache/apt/* /var/lib/apt/lists/* doesn't help.

They have been ignored, or old ones used instead. I trimmed the beginning a bit, but I'm pretty sure I left enough context. Does some package source need to re-issue their signatures? Is anyone else having this problem?

This got to be fixed.

ok, I started from scratch with only "compile.sh" in an empty directory. Unfortunately it still doesn't work, but by chance I saw a message which is not recorded in the logs: Get:595 http://httpredir.debian.org/debian/ wheezy/main wifi-radar all 2.0.s08+dfsg-1.1 [52.4 kB] Failed to fetch http://httpredir.debian.org/debian/pool/main/w/weather-util/weather-util-data_2.0-1_all.deb Hash Sum mismatch Fetched 295 MB in 43s (6787 kB/s) E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Free space: tmpfs 2.5G 624M 1.9G 25% /home/qt/armb2/output/cache/sdcard ...could this be the reason? How can I possibly fix it? Or is more data cached anywhere outside of the lib, sources and toolchains directories? I have searched for "fail" and "error" in the available logs, but the only logged one is at the end, when Mail fails.
