* Add 'on the remote server' to `file` parameter description
* Add example showing how to use the `file` parameter, with specific
language about the file's location being on the 'remote server'
* Only change to short IDs for delete
If the user specifies long IDs, use them for all commands except for
deleting a key. Need to use short IDs there because of an upstream
apt_key bug. Fixed in apt_key 1.10 (fix is present in Ubuntu 16.04 but
not Ubuntu 14.0 or some Debians).
Fixes#5237
* Check that apt-key really erased the key
When erasing a key, apt-key does not understand how to process subkeys.
This update explicitly checks that the key_id is no longer present and
throws an error if it is. It also hints at subkeys being a possible
problem in the error message and the documentation.
Fixes#5119
* Fix apt_key check mode with long ids
apt-key can be given a key id longer than 16 chars to more accurately
define what key to download. However, we can use a maximum of 16
chars to verify whether a key is installed or not. So we need to use
different lengths for the id depending on what we're doing with it.
Fixes#2622
Also:
* Some style cleanups
* Use get_bin_path to find the path to apt-key and then use that when
invoking apt-key
* Return a nice user error message if the key was not found on the
keyserver
* Make file and keyring parameters type='path' so envars and tilde are
expanded
- Use range instead of xrange.
- Use python3-apt package for python 3.
- Eliminate unsupported for/else/raise usage.
- Use list on dict.items when modifying dict.
- Update requirements documentation.
Also made non-intrustive style fixes (adding blank lines).
Importing a (sign only) subkey with apt_key module always fails,
however the actual keyring gets created and contains the correct keys.
Apparently the all_keys function skips the subkeys, hence the problem.
