Now that is is being published, suggest to add a large font note at the very top saying “Preliminary and in development for 20.04, contents may have errors and omitions.” This is similar to what we have always done at the old location when we published the preliminary before the release date. The note gets removed on release day.

Done! Thanks for the suggestion

We have added a PDF download link to the introduction section of this document. This PDF is refreshed on a daily basis. If anyone would like to snapshot the guide at any stage, please download and rename the PDF for your own use.

The PDF version of the serverguide has not updated. It has been well over 24 hours since I made and edit. I want to determine is the file name for the PDF will change, because it is odd and looks machine generated. Currently it is linked from the help.ubunutu.com base page where 20.04 preliminary has been added (but for some reason it didn’t publish last night, maybe tonight), but we won’t be able to do that if it changes.

I’ll add redirects to help.ubuntu.com for lts and stable serverguides to the new spots tomorrow, which should publish sometime Thursday.

EDIT: O.K. I’ll make the PDF link at help.ubuntu.com file name independent by using the same address as herein, instead of what it ends up as (duh).

fixed two more url mapping table entries.
I think I have tried every navigation link now, but am not certain.

Will add a navigation link back to this page, if I can figure it out.

Deleted the “Service - Introduction” topic as it was a filler page, “DNS TBD” was on there but that has an extra page now anyway. I also removed the link from the introduction to not fail on the removed page.

Some more cleanup of no more supported items around IRC and Mailman. Removed the pages and dropped the links from here. For Mailman I re-added links to the upstream setup guide with exim4/postfix on these pages.

Next I’ll re-order the index to keep introdcutions before the content. It doesn’t make sense otherwise and especially in the single-PDF that is generated it is awkward to read it in any other order.

Fixed another missing url entry in the mapping table.
This time I looked at the source code of a page (not that the actual page used matters) and searched for discourse, only finding the one expected reference. I also looked at the code manually.

I just added another page: Service - LDAP Access Control

I hope I did it correctly this time

Any chance of getting an ePub format as well?
I’d love it if I could read it on the road and PDF is not a good format for that…

Hey there. The links in the main content of https://ubuntu.com/server/docs are broken. For example: https://ubuntu.com/t/installation 404s. The sidebar links are working.

Upon further inspection it looks like all of the https://ubuntu.com/t/… URLs are 404ing. Specifically I was interested in virtualization (https://ubuntu.com/t/virtualization-introduction) when I found that many of the links aren’t working.

Hi Jrmyck, thanks for pointing out the broken links! They should be fixed now. This table of links on the Intro page is new, and still a bit work in process. I’d appreciate if you’d doublecheck and notice if any are still incorrect, or if there are any other necessary improvements for the front table links.

Greetings
Still an issue
404 ubuntu 16 docs
404 ubuntu 16 server pdf as well

Are there official alternatives from Canonical or do we find a third party host for this? - If so. A link here would be of help please.

Thank you everyone.

I removed the links to the 16.04 documentation, as it was deleted from help.ubuntu.com when it became EOL (End Of Life) earlier this year. I forgot about these links at the time.

I keep some old copies of help.ubuntu.com, as it was on some dates, on my web site. I also use it to preview pending updates to be sure we didn’t make a mistake. @food4doug, you could get 16.04 docs there. I encode the link below to prevent the barrage of bots that come whenever I post a link:

The PDF does not appear to be updating, at least not daily.

The PDF still has not updated. It also doesn’t seem to include screen shots.

Now that we want to start preliminary publications of 22.04 LTS documentation, it is time to create the required infrastructure in this disclosure version of the serverguide to continue to support 20.04 while also publishing 22.04, and in 2 years 24.04.

The PDF is still not updating.
