If you browse to explainshell.com and paste shell commands that you don't understand, it parses the commands and gives excerpts from relevant docs, which might help you in future. I pasted your two command above, and received the following results.

Re: standard way of installing audacity documentation on debian stretch, is there a package?
:) Thanks David!! In the ubuntu bug tracking system, at least iirc, there's a place you can click to indicate 'This affects me too'. Is there any way of doing this for debian? Anyhow, thanks again for informing me of the situation. dan On Sun, May 28, 2017 at 12:23 AM, David wrote: > On 28 May 2017 at 14:19, Dan Hitt wrote: >> I installed audacity on my debian 9 (stretch) system. > > [...] > >> There are remote links offered, of course, but i would like the >> software to function as designed, so i assume there must be some >> package that has the audacity docs? > > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=313038 > > 2005 wishlist bug reported > 2009 response: wontfix > 2017 ?

I don't know what they are. I just thought about this. I've been uploading these packages under the 'main' component name. What if I uploaded the packages under a 'nightly-$(date)' component name instead? In theory if I have my sources.list setup right, the my-app and app-configs would need to change their package name to include the version. It would also mean that they only find each other, right? I haven't tested this theory out. Sijis

The question I have is > which one do I have to consider ? Domain-validated (i.e. they just check you can receive email at the domain, or that you can put something int eh domain's DNS) TLS certificates are all pretty much the same. Your worst case scenario is that the certificate authority is found to be hopelessly insecure and is distrusted by one or more major browsers. I suggest it is worth your time to get letsencrypt automation working and just use those, for free. If you need extended validation for some reason then the costs will vary, pick any big name. You'd probably know what to do already if this were a requirement though. > Recently came to the market some lowcoast ssl certificate providers. Or free > ssl providers.

You get a similar problem when you zero out an entire hard disk No, it is a completely different problem. It destroys partition tables, partitions and filesystems, not drive identification. and there the solution is to manually enter into the bios the hard drive.

I will say that for the EV certificates at Comodo, they do seem to do their "due diligence" and properly verify the purchaser's identity, at least if it's corporate. But the EV certs are more expensive of course. For the free providers, I've never heard anything bad about letsencrypt.org but I haven't personally used them..Nick
