#10295 — apt.Cache.update with alternative sources.list

Hi,

I need some access (as normal user) to an apt cache with an alternative
sources.list (those in /etc/blends/ installed by blends-dev), but I have
problems to find out how to use it.

I first tried to just specify the alternative source file:

```
>>> import apt
>>> c = apt.Cache()
>>> c.update('sources_list='/etc/blends/sources.list.testing')
LockFailedException: Failed to lock /var/lib/apt/lists/lock
```

Then I tried to use an alternative root directory:

```
>>> import apt
>>> c = apt.Cache(rootdir='/tmp/myapttmp')
>>> c.update('sources_list='/etc/blends/sources.list.testing')
FetchFailedException: W:GPG error: http://ftp.debian.org/debian testing InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7638D0442B90D010, E:The repository 'http://ftp.debian.org/debian testing InRelease' is not signed.
```

To which place in the new root directory do I need to copy the keyring?
I tried <<rootdir>>/usr/share/keyrings/ but this didn't work.

And/or how can I disable authentication (--allow-unauthenticated,
resp. APT::Get::AllowUnauthenticated)?

Version of python3_apt is 1.4.0~beta3+b1

Best regards

Ole

AFAIK, the apt trusted keyring is normally in /etc/apt/trusted.gpg +
/etc/apt/trusted.gpg.d

So, as long as you're sure the rootdir behaves as you think this should help
you to chose the appropriate place.

It's far easier to fight for one's principles than to live up to them.

If you want to completely isolate apt from the system configuration
for apt, the correct way to do that is to set the APT_CONFIG
environment variable. See apt.conf(5), APT_CONFIG is the first
mechanism used for setting the apt config and /etc is the second place
apt looks for configuration. If you do not want to override every item
(including hooks/etc) in every file in /etc/apt/apt.conf.d then you
need to use APT_CONFIG. Examples of how to do this include chdist
(from devscripts), apt-venv or the derivatives census codebase.
