Thanks a lot Yves-Alexis for reply and advice! > Also it's likely that > you need to ask this to Raspbian, not Debian.
Please give me a 2.nd try in this list. If it will become obviosly to be a problem of Raspbian I will change to them. > It would help to paste the exact error messages. The command "sudo apt -o Acquire::http::AllowRedirect=false update" ran fine. By apt "list --upgradable" these 5 packages are displayed: apt/stable 1.4.9 armhf [upgradable from: 1.4.8] apt-transport-https/stable 1.4.9 armhf [upgradable from: 1.4.8] apt-utils/stable 1.4.9 armhf [upgradable from: 1.4.8] libapt-inst2.0/stable 1.4.9 armhf [upgradable from: 1.4.8] libapt-pkg5.0/stable 1.4.9 armhf [upgradable from: 1.4.8] But by sudo "apt -o Acquire::http::AllowRedirect=false upgrade" I always got the following error messages after my confirm to install: Err:1 http://raspbian.raspberrypi.org/raspbian stretch/main armhf libapt-pkg5.0 armhf 1.4.9 302 Found [IP: 93.93.128.193 80] Err:2 http://raspbian.raspberrypi.org/raspbian stretch/main armhf libapt-inst2.0 armhf 1.4.9 302 Found [IP: 93.93.128.193 80] Err:3 http://raspbian.raspberrypi.org/raspbian stretch/main armhf apt armhf 1.4.9 302 Found [IP: 93.93.128.193 80] Err:4 http://raspbian.raspberrypi.org/raspbian stretch/main armhf apt-utils armhf 1.4.9 302 Found [IP: 93.93.128.193 80] Err:5 http://raspbian.raspberrypi.org/raspbian stretch/main armhf apt-transport-https armhf 1.4.9 302 Found [IP: 93.93.128.193 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/a/apt/libapt-pkg5.0_1.4.9_armhf.deb 302 Found [IP: 93.93.128.193 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/a/apt/libapt-inst2.0_1.4.9_armhf.deb 302 Found [IP: 93.93.128.193 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/a/apt/apt_1.4.9_armhf.deb 302 Found [IP: 93.93.128.193 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/a/apt/apt-utils_1.4.9_armhf.deb 302 Found [IP: 93.93.128.193 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/a/apt/apt-transport-https_1.4.9_armhf.deb 302 Found [IP: 93.93.128.193 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? I tried to use a command with --fix-missing but this didn't work. Maybe I used the wrong syntax. > Can you provide the links you used and the hash it gives you locally? This was a second problem when I tried to solve it by manual instalaltion. For the downloads I used the links you have posted and found some dismatched hashes in these files: apt-dbgsym_1.4.9_armhf.deb Local Hash = 734604633a87aac1b6bdf1ded6ed9a398122be8654690e6acc9a195c3d6dab14 apt-utils-dbgsym_1.4.9_armhf.deb - Local Hash = 42b07cdf359a7dcca06533bb3672039b62cd850a3f65d63f9a92ed6ed20537f1 libapt-inst2.0-dbgsym_1.4.9_armhf.deb Local Hash = 35044d57c7832041eb212fdab5893dc168b25ab4f7f6f50e00a471ac9f7213dc libapt-pkg5.0-dbgsym_1.4.9_armhf.deb Local Hash = d4e59e53e471b11c2bcd1ecf39f71bb50214b97ba492ba7b767301816266ce37 But meanwhile I see that I don't need those files because they are obviosly not displayed by apt --upgradable list. And the hashes for the 5 needed packages seem to match. > Try dpkg - -l |grep apt dpkg --list |grep apt worked for me. That's the result: ii apt 1.4.8 armhf commandline package manager ii apt-listchanges 3.10 all package change history notification tool ii apt-transport-https 1.4.8 armhf https download transport for APT ii apt-utils 1.4.8 armhf package management related utility programs ii aptitude 0.8.7-1 armhf terminal-based package manager ii aptitude-common 0.8.7-1 all architecture independent files for the aptitude package manager ii firmware-realtek 1:20161130-3+rpt4 all Binary firmware for Realtek wired/wifi/BT adapters ii libapt-inst2.0:armhf 1.4.8 armhf deb package format runtime library ii libapt-pkg5.0:armhf 1.4.8 armhf package management runtime library ii python-apt-common 1.1.0~beta5 all Python interface to libapt-pkg (locales) ii python3-apt 1.1.0~beta5 armhf Besides according to your recommendation I tried this too: deb http://cdn-fastly.deb.debian.org/debian-security stable/updates main in /etc/apt/sources.list. But running an update command an error showed up that the key doesn't match, so this failed too. So please let me know - what is your conclusion? It's a question for Raspbian - and I should ask there now? Or can I install the 5 upgrade files qouted above manually without greater danger of a system crash? What do you recommend to be the very next step? Thank you in advance. Edgar
