Public bug reported: I have apt configured to load a wide variety of sources; my apt is using a local squid-deb-proxy on the same system, and the source that is failing is hosted on an archive mirror on my LAN.
Today I noticed unexpected results from apt-get update: # apt-get update Hit:1 http://wopr/ubuntu bionic InRelease Hit:2 http://wopr/ubuntu bionic-updates InRelease [...] Get:45 http://archive.canonical.com/ubuntu precise Release.gpg [181 B] Hit:46 http://ftp.debian.org/debian stretch Release Ign:26 http://wopr/ubuntu precise Release.gpg Ign:49 http://wopr/ubuntu precise/restricted Sources Ign:50 http://wopr/ubuntu precise/multiverse Sources Ign:48 http://wopr/ubuntu precise/main Sources Hit:49 http://wopr/ubuntu precise/restricted Sources Ign:50 http://wopr/ubuntu precise/multiverse Sources Hit:51 http://wopr/ubuntu precise/universe Sources Ign:51 http://wopr/ubuntu precise/universe Sources Err:50 http://wopr/ubuntu precise/multiverse Sources Could not open file /var/lib/apt/lists/partial/wopr_ubuntu_dists_precise_multiverse_source_Sources.bz2 - open (13: Permission denied) [IP: 127.0.0.1 8000] Ign:29 http://ftp.debian.org/debian unstable InRelease Ign:48 http://wopr/ubuntu precise/main Sources Ign:34 http://ftp.debian.org/debian testing InRelease Ign:45 http://archive.canonical.com/ubuntu precise Release.gpg Hit:55 http://archive.canonical.com/ubuntu precise/partner Sources Ign:55 http://archive.canonical.com/ubuntu precise/partner Sources Hit:55 http://archive.canonical.com/ubuntu precise/partner Sources Fetched 670 kB in 7s (101 kB/s) Reading package lists...
