Issue:
Required pyparsing version
I've been experimenting with writing tests using the oldest allowed versions of our Python dependencies. `setup.py` for `letsencrypt-nginx` says it requires `pyparsing>=1.5.5` but when I pin version 1.5.5, I encounter problems. You can see Travis logs of the issue [here](https://travis-ci.org/letsencrypt/letsencrypt/jobs/100739657) and [here](https://travis-ci.org/letsencrypt/letsencrypt/jobs/100739658).

We should determine what version we require and update `setup.py` accordingly.



Discussion:
This seems like a good idea to do. Putting it in the milestone so we remember it exists.
We've made a lot of changes to Certbot since this issue was opened. If you still have this issue with an up-to-date version of Certbot, can you please add a comment letting us know? This helps us to better see what issues are still affecting our users. If there is no activity in the next 30 days, this issue will be automatically closed.

Issue:
ocsp verification is not working behind proxy
When running certbot behind everything is working well by setting the http_proxy environment vars except ocsp verification task. 
openssl doesn't used http_proxy environment  var but it's possible to add "-host" parameter to set a proxy. It would be good to patch the code and when http_proxy environment var is defined add the '-host' parameter when calling openssl.



Discussion:
A solution like you described sounds good to me. We should probably try to properly handle both `HTTP_PROXY` and `HTTPS_PROXY` though. Are you interested in writing a PR?

Issue:
Fix rebuild dependencies to include python version constraint (for enum)
We have code to do this, but it seems to no longer be working. This came up in the process of testing https://github.com/certbot/certbot/pull/8026. Until it's fixed, we have to remember to manually add the constraint whenever we run `rebuild_dependencies.py`.


Discussion:
@adferrand, I see there's a TODO around [the relevant line](https://github.com/certbot/certbot/blob/master/letsencrypt-auto-source/rebuild_dependencies.py#L45); did we already know that this is broken?
Looks like the enum specification was originally eaten [here](https://github.com/certbot/certbot/pull/7337/files), along with an additional comment at the top with instructions.

Issue:
Deprecate Python 3.5 support
Python 3.5 is scheduled to reach its end of life in September. See https://devguide.python.org/#status-of-python-branches.

To stay ahead of the curve, I think we should deprecate support for Python 3.5 now and then remove support for it in our release in the beginning of September.

You can find an example of how we've done this in the past at https://github.com/certbot/certbot/pull/7378. In addition to what was done there though, since there is some support for using Certbot as a library, I think we should add a warning to Certbot's `__init__.py` like we do in `acme` too.

Issue:
Add a --preconfigured-renewal flag
We should create a `--preconfigured-renewal` flag that we can set in environments where Certbot should have automated renewal preconfigured. Feel free to change the exact name of the flag. It's just the first thing that came to my mind.

The idea here is we can then modify Certbot's output about renewal based on this flag. This flag should have `help=argparse.SUPPRESS` set because it's not something that users should mess with.

Things that should be done here as part of this:

- [x] Set this flag in `certbot.wrapper` for snaps.
- [x] Document this flag in https://github.com/certbot/certbot/blob/master/certbot/docs/packaging.rst.
- [x] Ping Certbot's Debian packager about this telling them the syntax for them to use to set the flag in `/etc/letsencrypt/cli.ini` and in what release it will be added.

I think actually changing Certbot's output based on this flag can come later.


Discussion:
I would like to challenge the need of a flag for that. One may consider that flags on CLI or for users, not packagers who need to change some internal logic to the program. In that extent, something less committing like an environment variable could be sufficient for that purpose?
I discussed this with Harlan in our public Mattermost channel and he said a flag would be easier to implement such that it would be set for all invocations of Certbot so I think a hidden CLI flag is the best way to go here.

Issue:
Check that calls to external processes have output redirected
This will be similar to what was done in https://github.com/certbot/certbot/pull/8237. Searching for `subprocess` and `Popen` is probably a good start to finding these calls, though we may use other ways of calling externally in the codebase. None of these calls should print directly to the terminal.

Issue:
Deprecate Apache 2.2 support
With [CentOS 6 reaching it's EOL at the end of November](https://wiki.centos.org/About/Product), I think we can deprecate Apache 2.2 support. No non-EOL'd versions of CentOS, Debian, or Ubuntu still package Apache 2.2 and it is different enough from Apache 2.4 that removing support for it is good from a maintenance perspective.

This issue is just tracking printing a warning when Apache 2.2 is used while https://github.com/certbot/certbot/issues/8461 is tracking actually removing support in a new major version of Certbot.

Issue:
Log the real path to the running certbot executable
This was suggested at https://community.letsencrypt.org/t/add-the-run-from-path-to-log/134964

I think it's a good idea for the purposes of forum investigations. Might come in handy as certbot-auto is deprecated and as users migrate to snaps.


Discussion:
Would using `sys.argv[0]` suffice? On my system it returns `/usr/lib/python-exec/python3.8/certbot` due to the use of [python-exec](https://github.com/mgorny/python-exec/). I have no idea what the return values would be for distributions other than Gentoo, Snap or Windows, so it's difficult for me to say if `sys.argv[0]` is the way to go.
I think that'd be fine, since this is [just for debugging purposes](https://github.com/certbot/certbot/blob/38893115572ee1bc91fcaf10669a80686795ba0b/certbot/certbot/_internal/main.py#L1384-L1387). 

Even if `sys.argv[0]` returns something unintuitive like a `python-exec` path, it's still useful information to disambiguate *which* Certbot ran.

Certbot already uses `sys.argv[0]` in a couple of places ([1](https://github.com/certbot/certbot/blob/38893115572ee1bc91fcaf10669a80686795ba0b/certbot/certbot/_internal/main.py#L207-L215), [2](https://github.com/certbot/certbot/blob/38893115572ee1bc91fcaf10669a80686795ba0b/certbot/certbot/_internal/main.py#L948-L950)) for display purposes, but as you point out, the output can get weird. This is on my list of things to investigate.

Discussion:
@adferrand, having reviewed #8530, do you happen to know what should be done here?
It is due adding man dir to exclude_patterns in conf.py:
https://github.com/certbot/certbot/commit/7399807ff2b4f8ac1f97e4f037f374610ca88797

```
exclude_patterns = [
    '_build',
    'man',
    'challenges.rst',
    'ciphers.rst'
]
```

removing man from the list resolves the problem.

As the author of #8530, this one is on me. I didn't test building the man page. I'll dig into it and see if I can get this fixed.
