Core & TKLDev v17.0 Stable Release & "preliminary" RPi3/4 builds
2022-05-17 Update: All affected appliances have now been bugfixed and rebuilt as v17.1. The v17.x release will continue, with all new appliances to be released as v17.1.
Important announcement: A serious bug has been discovered in v17.0. Everyone running v17.0 is advised to follow the directions as noted to fix the immediate bug. Due to this issue, the v17.0 release has been halted for now. v17.0 download links have been removed from appliance pages. Production will resume ASAP, first with the re-release of fixed v17.0 appliances; as v17.1. Then with the remainder of the library (all appliances will be v17.1 - including those not previously released as v17.0).
Also, please note that Raspberry Pi builds are NOT affected!
Update 2022-04-27: Please see the second instalment of the v17.0 release.
I'm excited to finally announce the stable release of Turnkey v17.0. It's been a bit of a slog, taking way longer than I had hoped and there are only two this time. Regardless, we've finally made it to the stable release milestone, at least for Core and TKLDev. Hopefully we can keep the momentum up and have more v17.0 appliances ready really soon!
In the meantime, these 2 new v17.0 appliances are published to our mirror network and are also available for download direct from their relevant appliance pages (app page links above, direct download links below) or launched directly from the Hub.
Finally, whilst I can't take any credit at all, I'm super excited that community member, Yannick has produced "preliminary" Raspberry Pi 3/4 builds! I've only just ordered mine, so I can do some testing and hopefully get "official" RPi builds released sometime soon. If you have an RPi3 or 4 (including '400'), please do download an image and give it a test drive. I'm sure that Yannick would welcome some feedback, considering all the hard work he has put in developing this from scratch! [edit: we've just realised that the image Yannick created supports both RPi3 & RPi4]

Changes of significance
As per previous TurnKey major version releases, the biggest change is the Debian version that this TurnKey release is based on. TurnKey 17.x release is based on Debian 11/Bullseye. As noted in the release candidate announcement the main changes have generally been at the software level, although much of the work will likely not be immediately obvious to an end user. Most of the python2 to python3 code updates occurred in v16.x, however, much of our build infrastructure (including tools in TKLDev) was still python2. So there has been some significant work on the tools in TKLDev (particularly fab and pool). In other instances, we have done some general software maintenance and implemented some bugfixes and/or code cleanup in our software.
Otherwise, we inherit the updated Debian packages. As per usual, upstream software will be refreshed (where relevant - neither of these apps include upstream third party software). There have also been a myriad of bug fixes applied and feature requests implemented. You can view the full changes that (will) apply to all v17.x appliances (to both these and the upcoming batches) via the Core v17.0 changes. The specific TKLDev changes are on top of that (shared changes common to all appliances are all noted in the Core changelog).
Beyond all the updated Debian goodness and custom TurnKey software improvements, v17.0 brings a new Webmin version (currently v1.990) and a number of changes with the intention of making TurnKey more IPv6 friendly (mostly thanks to community member, Richard van Dijk). We're not completely there yet (e.g. TurnKey's apt repo is STILL not available via IPv6) but at least there is some progress (FWIW, once v17.0 release is complete, I plan to focus on getting IPv6 working with our apt repo).
And to give it one more plug, (because I'm so excited about it) if you have a Raspberry Pi 4, please do go have a look at Yannick's RPi4 thread. Whilst it isn't (yet) official TurnKey, Yannick has been on and off involved with the TurnKey Community for a few years now and his efforts have been greatly appreciated. If you do give that a go, please be sure to post feedback on that thread. Even if everything works exactly as you expect, we'd love to hear that confirmed!
Launching from the Hub
For now, the Hub will still launch v16.x appliances by default (mostly because there are only 2 v17.0 app so far). At some point, once we get a few more loaded, we'll make v17.x the default (and eventually remove v15.x altogether). In the meantime, it's really easy to launch these 2 new apps (and the upcoming ones as they get added) in their v17.0 incarnation. You can click this link to launch a new v17.0 server. Otherwise, look for the "17.x" text link in the top right corner when logged into the Hub (just below "logout"):

Where are the other builds?
Due to the time it's taken to get to this point, we've decided to focus primarily on getting the appliances updated and released ASAP. As such, we'll only be publishing ISO and Hub (AWS EC2) builds initially. I know that this won't suit all of our users and we deeply apologise in anticipation. The rationale for this move is that the ISO build can be installed almost anywhere and the Hub builds provide our primary source of revenue (which keeps the lights on). Furthermore, with all appliances published as ISO, once we update and test the build code for other builds, pumping out the alternate build formats should be fairly straight forward. So focusing on the ISO and AWS EC2 builds first seems like a reasonable balance between what we'd ideally like (publish everything together) and giving the community the maximum value, at the soonest possible moment.
In the meantime, if you REALLY need/want a specific build, please feel free to share which one. I can't offer any guarantees, but at the very least, I'm more than happy to assist you testing to see if the existing code works (if it does, great - if it needs update, then we'll play it by ear).
Just to be clear, we do intend to publish other builds. I just can't give firm timeframe on when they'll be available. As I say above, if that doesn't suit you, feel free to share your feelings (although please keep it classy). If we get big enough pushback from you, then perhaps we'll need to reasses?
Stuff that didn't make it...
There are always tons of things I try to cram into a new release. I try to close as many issues as possible, focusing first on the bugs, but also trying to implement feature requests and make any other improvements we can along the way. Much of this work occurs behind the scenes and most community members probably have no idea of how much agonising occurs when it comes to deciding what to keep working on (trying to include), and what to leave until next time.
One of the bigger features I had hoped to include in v17.0 was UEFI boot/install (ISO) support. Unfortunately we ran out of time and I just can't hold v17.0 back any longer. I do hope to circle back to that at some point, as IMO it would make TurnKey more useful if it could be installed on newer hardware. I had also hoped to have the IPv6 apt repo ready for the v17.0 release. That won't make it either, but it doesn't actually doesn't depend on other stuff, so it's only a matter of waiting until I have a few spare cycles (haha I hear you say...).
It's perhaps also worth noting that TKLBAM is still python2 in v17.0. We have made some steps towards porting it to py3, but again we didn't want to hold up v17.0 any longer. Plus because TKLBAM is such a pivotal and important component, we can't afford to rush it and really do need to ensure that we test the heck out of it! The plan at this point is to pivot back to TKLBAM dev once v17.0 stable release is finished, and keep working on the update. Our current intention is to release "TKLBAM 2.0" within the lifetime of v17.x. Initially both TKLBAM & TKLBAM2 will be available side-by-side. Once we get to v18.0 (or perhaps before?) we will have TKLBAM2 only. Obviously the plan is open to changes, but I wanted to raise the curtain a little so you have some insight into our plans.
Please help test and give us your feedback
As per always, we'd be super happy if you gave these appliances a spin. Ideally, we'd love to hear how great they are. But obviously we'd also like to really hear of any issues you hit, any bugs we missed (or new ones we've introduced) or any other thoughts or feedback about v17.0.
If you aren't happy about no OVAs yet, features we're missing, or things we should have included but didn't, let us know! Obviously keep it respectful, but we always love feedback! :)
We haven't updated the bt-container script for v17 yet, so I'm not sure how that will go. But if you build for v16, it should "just work"! (note that you will want to make sure that you check out the '16.x' branch of both common and buildtasks).
And if you generate a v16.x ISO and ensure that it works properly as an ISO, then building your ISO to LXC (via bt-container) it should work.
Getting stuck at basic.target is a bit strange! Have you tried entering the container from the host (assuming Proxmox, via 'pct VMID enter')? Perhaps you can get in that way and see what is going wrong?
