Cannot install SPFX package using Site Scripts

We’ve noticed that for at least 5-6 days, we can no longer install SPFX packages using Site Design. Here is the very minimum sample that replicates the issue:


{     "$  schema": "schema.json",     "actions": [         {             "verb": "installSolution",             "id": "{AppPackageId:ContosoCentral}"         }             ],     "version": 1   } 

Error message:

enter image description here

SPFX package is deployed to the App Catalog with no errors:

enter image description here

Installing the SPFX app without Site Designs works perfectly fine:

  • Does anyone have the same issue (please, reply in comments)
  • Main question: Is there a workaround for this? Anything we can do to solve it?
  • Is there a way to get more information about the error? Install SPFX Solution: Something went wrong and we could not complete this action sounds awefully unhelpful.

Any help will be greatly appreciated!


I’ve found related issue in GitHub: Cannot Install SPFx Solution or Activate Custom Feature using a Site Design #3543, but I don’t see any resolutions.

I cannot set DejaVu Sans Mono in gnome-terminal

The problem:

When I try to select the font, there is no regular DejaVu Sans Mono, only the bold, book, and oblique variations. Here a screenshot. However, if LibreOffice Writer shows the font, and I can use it without any issue on it.

I installed all the ttf-dejavu packages sudo apt install ttf-dejavu*

My System:

Ubuntu 19.04 64-bit. GNOME 3.32.1

Not so related questions:

  • I don’t want a possibly “fake” variation, but the regular font: cannot see bold in gnome
  • The OP starts saying that is able to see the font in gnome-terminal: ttf-dejavu fonts in xlsfonts

Thanks in advance

Modular Abilities: If Link cannot connect a disadvantage to an advantage, how does one associate them?

I want to run a superhero game with Modular Abilities that trigger themed disadvantages. For example, the advantage “Flight” would trigger the disadvantage “Cowardice“; the advantage “Damage Resistance” would trigger the disadvantage “Berserk“; the advantage “Telecommunication (Telesend)” would trigger the disadvantage “Truthfulness“; the advantage “Invisibility” would trigger the disadvantage “Kleptomania.”

On page 106 I see that “Link” is meant to link multiple advantages. Thus I need a rule to link a disadvantage to an advantage. One approach might be to simply note that the two effects always go together and to deduct the points of the disadvantage from the advantage. Thus Telesend with Truthfulness would be 30-5 points for a total of 25 points. I suspect that GURPS already has a canonical way of doing this, however.

Software installation problem: cannot adding path to /usr/local/bin

I am currently installing a software in a local directory(/some/local/directory/bin/). I tried to copy it into the usr/local/bin/ but I am not allowed. I am wondering that how can I execute the software? Is it possible to not have its path added to the usr/local/bin?

(I’m trying to install samtools. So if i can successfully install it into local/bin, I should call “samtools command file” to let it execute. But now that I can only install it into a local directory/bin, what should I call in order to execute it?)

What do I use as an alternative to Domain-Driven Design, if I cannot define a Competitive-Advantage area of my system to apply it?

From all I read and watch, Domain-Driven Design (DDD), is a costly and time-consuming endeavor. In fact, everyone I have seen, including Eric Evans and Greg Young, say, don’t use DDD except where you have a “Competitive Advantage.” To find that advantage it kind of drops off into various discussions of business and T-Shirts. That’s fine. I understand that’s a business decision, not necessarily DDD proper, though DDD helps identify it.

What does a company do with the non-Competitive aspects of their system that they simply cannot buy off-the-shelf software for?

For example, an inventory program. Lots of companies have inventory programs. Most of them have the same features. It’s marketing that separates most of them and reputation. For DDD, I don’t know these all have any Competitive Advantage.

Where does DDD fit into these scenarios? I’d really like to use DDD because I like its principles, but I am finding it makes little sense, at least for me, given the caveats of the proponents.

So, I am right back where I started with other design methodologies (not that they are bad.) And, I use the word “methodologies” loosely because DDD is more about principles, as so many “methods” are. I can only take principles here (Ubiquitous language and so on), but not much else.

What do I use as an alternative to Domain-Driven Design, if I cannot define a Competitive-Advantage area of my system to apply it? Should I use DDD anyway? Doesn’t seem like it.

What I really don’t get is when does someone not use an analyst or the like to understand a business. How else would the developers know what to write? That’s not DDD; that’s just common sense.

Not asking about tactics here, but rather strategy (as some I have read word it.)

Example from Vaughn Vernon,

Speaking about the Entity Framework and DDD, “Just allow Entity Framework to map entities and get back to what will make a difference in this competitive world: your market-distinguishing application.”

It seems like DDD is not for 90% of the world, only the Magic Quadrant.

Cannot boot Windows 10 after Ubuntu installation

So I was having this idea that I’ll install ubuntu 18.04 alongside my already working win 10.

Keep in mind that I have two older discs (MBR) and legacy bios – main disk 1 TB. On my main disk a made some free space, shrank size making 50GB of free space for Ubuntu instalation. I installed Ubuntu from usb and after that it asked for reboot so I did that. And that’s where first problems appeared.

First, I was not able to boot back to ubuntu at all. After some tinkering I found out on the internet that I should be using EasyBCD as boot manager. Did that, added ubuntu, corresponding partition and I got it. Reboot, boot manager loads fine, win10 working as it used to. But when I tried Ubuntu, I got stuck on black screen with flashing cursor. Was not happy with that. Went for reinstall as someone suggested that something might install wrong. So I deleted the 50GB partition (made free space again) and reinstalled Ubuntu back.

This time really something was running differently. First Ubuntu boot manager welcomed me with all various choices. (Ubuntu, recovery mode, win10 on older disc and win10 on main disc). Tried ubuntu, everything was running flawlessly. But when I tried to boot back to Win10 on my main disc, boot manager appeared with my message that I should repair my pc. And following \NST\nst_linux.mbr is missing or error in it. From this point I cannot really move further. Ubuntu is still running fine. I’m able to run Win10 on older disc but when I try to boot using main one it ends on this message.

I’ll be very greatful if anyone provides any idea how to fix my problem without scraping main storage.

I had an idea if there is some interference with ubuntu boot manager and EasyBCD that is surely still working on the storage. Also I went through the directories via ubuntu bash and at this point I did not lose anything from the main storage.
