[Bug 1658027] Re: pkgcache.bin. files fill up drive

2017-01-30 Thread Darren Conway
Hello

In the /etc/apt/apt.conf.d/10periodic file I set:
APT::Periodic::Enable "0"
to disable update/upgrade script.

This stopped the generation of cache files.
Still nothing is recorded in the apt log files.

[Bug 1658027] Re: pkgcache.bin. files fill up drive

2017-01-22 Thread Darren Conway
Hi
Thanks for you prompt response.  Given the age of the version I am running, I 
have low expectations around corrective action.  I did read up bug reports 
where this issue was fixed prior to the release I have.  

On a slightly wider issue, I have attempted to conduct troubleshooting
on this problem.  My "findings" include:

 - no known Linux application that will identify what process/program
has created any given file.

 - I don't know of any marker that apt and related utilities might
include in a file to identify the source utility.

 - I have looked at the /etc/apt/apt.conf/10Periodic file and turned on
verbose "3" mode.  No email was created when the cache file was created
a 6:25am.

 - The MaxSize is set to "500" which is well under the capacity of the
HD.  Whichever program creates the cache files is ignoring the directory
size limit.

 - The problem appears to have developed spontaneously without user
intervention.

 - If there is a problem with a broken file, I don't know how to find it
or fix it.  Running "clean" gets rid of the cache files but doesn't stop
them being created.

In short, troubleshooting apt problems seems to be more difficult that
it should be. Perhaps this may be an area worth working on in future
releases.

In the mean time, I will just set up a daily cron "clean" job to clear
the cache.  I don't expect any action or further discussion.

Cheers

Dazz

[Bug 1658027] Re: pkgcache.bin. files fill up drive

2017-01-22 Thread Julian Andres Klode
This does not happen only with apt-get update. A new temporary file is
created by (almost) every APT command if at least one of the main cache
files is outdated. It is then renamed to the final file. If APT exits
before the rename, the temporary filename might stay around until you
run clean. Given that this only started 6 months ago, something must be
trying to read information from the apt cache.

Given that we are talking about a 4 year old release that has its end of
life in 3 months, I'm not going to spend any time investigating this.
There have been a ton of changes in 4 years, and I do remember some
cleanup in that area, and there have been no other reports about that
AFAIK with recent releases.

That said, if you can find the cause and reproduce this in 16.04, we
might be able to do something about it. But it's of course difficult:
There will always be some temporary files remaining if APT crashes in
the wrong moment. If you run a command and interrupt it with Ctrl+C,
there will likely be a file laying around, and there is really nothing
we can do about that.
