Trouble installing and uninstalling dotnet-ef - system-error

Nobody can solve this problem in the discussion and it's been going since July. None of us can download the application/tool we need and we all have the same problem. Please help.

I fixed the issue. If you have this problem, you should check your global.json file and make sure you reduce it from 5.0.0 to 3.1.10, because the 5.0.0 version is still in beta and does not properly support dotnet-ef yet.

Cypress freezing (Your tests are loading)

Cypress for me is often stuck in the "Your tests are loading" screen. I am really confused as to why it happens, and restarting Firefox/crome doesn't help either. It doesn't depend on any code, happens completely randomly and today my luck was down so I was looking more at that then at my code. any help is welcome, and thank you in advance.
Late reply, but are you using webpack-preprocessor? I am and the same issue happened to me when I upgraded to Webpack 5 lately.
The solution was to downgrade to Webpack 4.
In this case it is a known issue, there is an open Pull Request on Cypress github that should hopefully fix it: https://github.com/cypress-io/cypress/pull/15611
If you're coding a project that's using another version and you install the project without using nvm use it will install the latest dependencies which may break the code that doesn't support the new dependencies version.
Check the original code Webpack version and be sure it is the same installed locally

The "User7ZipPath" parameter is not supported

Recently, I have been getting this error a lot and from some research, I got to know that the cause for it is the Xamarin.Build package.
The error text is as follows:
The "User7ZipPath" parameter is not supported by the "XamarinDownloadArchives" task. Verify the parameter exists on the task, and it is a settable public instance property.
I have tried the solution here and here but nothing helped.
My configuration is as follows:
Xamarin version: 4.7.10.38
Visual Studio 2015
The Error occurs when I update the xamarin build NuGet package, If anyone has a solution to this problem please help me.
Thanks.
At last after all this time I was able to solve this problem.
The problem was with Xamarin.Build.Download package.
Now this package had a problem in version 4.7 where it is unable to find the XamarinDownloadArchives task.
I checked a lot of places and for the answer but nothing seemed to help with this issue after that I removed the bin, obj folders for all my projects.
And Updated my Xamarin.Build.Download package to version 0.4.11 and everything started working.
I hope this helps someone else, In case of any queries related to this issue feel free to comment.
Finally! I've come with a solution. The problem was in the Xamarin.Build.Download package, v0.4.0. It was a annidated dependency (in iOS) of Xamarin.Forms.GoogleMaps v2.2.1.
Updating Xamarin.Forms.GoogleMaps to v2.3.0 (the most recent version as of today) solves the issue. Make sure to clean the solution after update NuGet dependencies, though.

ocramius/proxy-manager dont work with php 7.0.12

i have some error with my application symfony. one error is Unsupported declare 'strict_types'. Please help me to resolve that.
My php version is 7.0.12
My symphony version is 2.7.16
My Ocramius/proxy-manager version is 2.0.3
this is the link to my server : http://www.kossa.cm
I actually encounter the exact same issue and the only ugly fix I could find to just pass through (without fixing it) is to remove that vendor/ocramius/proxy-manager folder and do not run a composer update (that would install the proxy-manager back).
As I said, it is not a proper fix, I'm trying to solve it now.
If you found any kind of information about it, please share it with us ;)
--Edit-- Are you using wamp ?
to solve your problem, downgrade your php version to 5.6, because ocramius is not compatible for the momment with php 7.0 and above!

There is no suitable CSPRNG installed on your system

I have a problem with my laravel website while I am hosting it to online server it gets an error says
There is no suitable CSPRNG installed on your system
I searched the question. But I found nothing that helps me.
Please if someone know how to handle this problem I will be so grateful. Thank you!
The program is coded with laravel 5 and php 7
I also got surprised by this error after upgrading Symfony. Try this article, the first solution fortunately worked for me:
How to solve PHP 7.0 Polyfill : There is no suitable CSPRNG installed on your system - paragonie/random_compat:
Although you're not using directly this library, add it to your composer.json as a dependency. Require random_compat with the specific version 1.4:
{
"require": {
"paragonie/random_compat": "~1.4"
},
}
Then run composer install (or composer-update if you're already using this library) and try to run your project again. If it didn't work try downgrading to 1.3, if it doesn't work neither, then i hope you have the rights to modify PHP settings in your server and go to the next possible solution.
Have you tried these links

Seems like you are facing a similar issue.

XCode 4.0.0 Version instead of Xcode 4.0.2

I downloaded Xcode 4.0.2 just a while back. I am not able to connect to the repositories as I was able to do in Xcode 4.0.0.
I do not know the reason for this, and I think the settings are pretty much right. I am now searching for Xcode 4.0.0 so that I could revert back to the earlier version.
Does anybody know where I can find the earlier version of Xcode?
You can look on torrent sites, there may be some out there. Also, try searching Google for links from Apple, you may be able to figure out the download link from the most recent available on Apple.
Are you running Time Machine? You could revert to an earlier version from there.
