Title:
apt's lists/partial fills disk
Status in APT:
New
Status in apt package in Ubuntu:
Confirmed
Bug description:
Since I upgraded to vivid, apt fills the disk space at
/var/lib/apt/lists/partial. This was triggered by the automatic update
every day, and as a solution I killed the processes named `http`
spawned by apt, and removed the offending file from lists/partial
manually. Until now, `apt-get update` and `apt-get upgrade` had been
working. However, today, when I tried `apt-get update`, it got stuck
in some file, continuously increasing its size when at 100%.
I tried inspecting the file to see if there is a repetition of data,
and there seems to be, as I have suspected.
First of all, the file is it.archive.ubuntu
.com_ubuntu_dists_vivid_main_binary-i386_Packages.bz2 this time, but
I'm not sure if the previous time it was also this file.
I used `tail` and `hexdump` to figure out whether a certain pattern
shows up in the file. Here are some examples:
$ tail -c 200000
it.archive.ubuntu.com_ubuntu_dists_vivid_main_binary-i386_Packages.bz2 |
hexdump | grep '\<bbdf\>'
0000c80 8d9e 63ad bbdf 40a7 3f3e 2b4a 9b95 aa5a

0030c80 8d9e 63ad bbdf 40a7 3f3e 2b4a 9b95 aa5a
$ tail -c 200000
it.archive.ubuntu.com_ubuntu_dists_vivid_main_binary-i386_Packages.bz2 |
hexdump | grep '\<9b95\>'
0000c80 8d9e 63ad bbdf 40a7 3f3e 2b4a 9b95 aa5a
0010c80 8d9e 63ad bbdf 40a7 3f3e 2b4a 9b95 aa5a

0030c80 8d9e 63ad bbdf 40a7 3f3e 2b4a 9b95 aa5a
$ tail -c 200000
it.archive.ubuntu.com_ubuntu_dists_vivid_main_binary-i386_Packages.bz2 |
hexdump | grep '\<1234\>'
0002630 fd50 b08d 7082 1234 85b3 a61e 2921 e0cd
0012630 fd50 b08d 7082 1234 85b3 a61e 2921 e0cd
0022630 fd50 b08d 7082 1234 85b3 a61e 2921 e0cd
$ tail -c 200000
it.archive.ubuntu.com_ubuntu_dists_vivid_main_binary-i386_Packages.bz2 |
hexdump | grep '\<76a8\>'
000fa90 747d 76a8 078a 67b6 60d9 83f5 5ff3 787c
001fa90 747d 76a8 078a 67b6 60d9 83f5 5ff3 787c
002fa90 747d 76a8 078a 67b6 60d9 83f5 5ff3 787c
As you can see, it seems that after the error, a certain pattern seems
to repeat every exactly 0x10000 bytes. I attached a copy of those
0x10000 bytes that keep repeating (from an arbitrary offset).

Do let me know if I can test further to see what could be wrong. I'll
keep an eye next times the behavior repeat to make sure the file is
the same / the pattern is the same and I'll report back. If you think
the problem could be the Italy server, let me know and I'll try with a
different one.
