apt-get update fails to find security Release and Packages on local mirror

[gobo7]

i have built a local mirror for 16.04. apt-get update fails to find xenial-security Release and Packages files.

Reading package lists... Done                                                                                                                               
W: The repository 'file:/mnt/urepo/ubuntu1604/mirror/archive.ubuntu/ubuntu xenial-security Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch file:/mnt/urepo/ubuntu1604/mirror/archive.ubuntu/ubuntu/dists/xenial-security/main/binary-amd64/Packages  File not found - /mnt/urepo/ubuntu1604/mirror/archive.ubuntu/ubuntu/dists/xenial-security/main/binary-amd64/Packages (2: No such file or directory)
E: Some index files failed to download. They have been ignored, or old ones used instead.

both files are in the mirror. both are set to mode 644 along with their respective directory tree.

instead of the web server, i'm using an nfs mount. the only thing i can think of is my sources.list file is incorrect or missing an option.

deb file:///mnt/urepo/ubuntu1604/mirror/archive.ubuntu/ubuntu/ xenial-security main restricted multiverse universe

can anyone make a suggestion on what i'm doing wrong or missing?

thanks,
gobo

16.04 support ends in a few months. Is this issue really worth solving at ts point?

unfortunately yes, due to libraries and kernel version. it is the reason i built the mirror.

When I examine my sources.list file I see similarities.

This looks about right.

deb file:///mnt/urepo/ubuntu1604/mirror/archive.ubuntu/ubuntu/ xenial-security main restricted multiverse universe

But this looks a different path. Or am I misunderstanding?

/mnt/urepo/ubuntu1604/mirror/archive.ubuntu.com/ubuntu/dists/xenial-security

And so does this.

mnt/urepo/ubuntu1604/mirror/archive.ubuntu.com/ubuntu/dists/xenial-security/main/binary-amd64

Extra directories, yes? Where is the release file? Is it in .../mirror/archive.ubuntu/ubuntu/ ? That is where Update is looking. So, why the reference to archive.ubuntu.com/ubuntu/dists/xenial-security ?

Well, you did invite anyone to make a suggestion. And I am anyone.

the directory ".../mirror/archive.ubuntu.com/ubuntu" was made by apt-mirror. i should have included the statement from my mirror.lists (and didn't)

deb-amd64 http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse

under archive.ubuntu.com/ubuntu are two directories -- dists and pool.

the Packages file apt-get update is fussing about does exist:

/mnt/urepo/ubuntu1604/mirror/archive.ubuntu.com/ubuntu/dists/xenial-security/main/binary-amd64$ ls -l
total 11360
-rw-r--r-- 1 root root 8204866 Jan 12 00:11 Packages
-rw-r--r-- 1 root root 1896320 Jan 11 23:55 Packages.gz
-rw-r--r-- 1 root root 1521264 Jan 11 23:55 Packages.xz
-rw-r--r-- 1 root root     105 Jan 11 23:55 Release

on a test machine i didn't care much about, i just picked a package to install from the mirror. it worked. it installed the oldest version in the mirror not the latest. so that kinda tells me the directory structure is mostly correct. mostly???
