this should be fixed.

please delete paket.exe from AppData\Local\NuGet\Cache\Paket

[skolkerom]

I did that, but no success, unfortunately:

D:\Programming\SafeBookStore>dotnet nuget locals --clear all info : Clearing NuGet HTTP cache: C:\Users\rvishnyakov\AppData\Local\NuGet\v3-cache info : Clearing NuGet global packages cache: C:\Users\rvishnyakov\.nuget\packages\ info : Clearing NuGet Temp cache: C:\Users\rvishnyakov\AppData\Local\Temp\NuGetScratch info : Local resources cleared.

D:\Programming\SafeBookStore>.paket\paket.exe The remote server returned an error: (503) Server Unavailable. (Github - cached (temporarily ignore updates))

In addition, I run paket.exe itself, so my guess that nuget cache is not used in that case.

Some news.

If I try to run original bootstrapper file(named 'paket.exe'), then I get error 503 as described above.

But if I rename paket bootstrapper file to 'paket1.exe' and run it, then paket bootstrapper download paket.exe into the same directory where paket1.exe located (.paket directory). After that I can build the project usual way by running build.cmd.

Maybe the cause of that problem is the same names of the paket.exe itself and paket bootstrapper?

Though, there is a chance some problem with cache, but I couldn't address that.

@forki Sorry but I don't have any idea. I tried on a machine that never had paket installed to checkout the repo and didn't saw any problem

Magic mode is affecting the filesystem part of paket but not the downloading part that happens as before so there shouldn't be any differences there

Ok, I'll try to reproduce this error on another computer few hours later.

[skolkerom]

There is error only on my work machine. I can't repro issue on my home notebook.

[realvictorprm]

@skolkerom are you using any proxy?

[skolkerom]

@realvictorprm Yes, my work machine is behind corporate proxy.

[realvictorprm]

This could be a problem but I don't know details, @forki got maybe a clue.

[NullVoxPopuli]

I have this issue on master

[codehutch]

I had this issue on LInux today with clean checkout of latest version:

Error: SendFailure (Error writing headers) (Github - cached (temporarily ignore updates))

Workaround is:

mv .paket/paket.exe .paket/paket.bootstrapper.exe
.paket/paket.bootstrapper.exe

Then build as usual:

• ./build.sh run

I was having a similar issue when trying to build a project that works fine on one PC on another PC.

The remote server returned an error : (404) Not Found. (Github - cached)

It would be really helpful if it could tell us what resource it's trying to request at this point, but I'm not sure whether this is paket or dotnet that's reporting this failure.

For me, the fix was to comment the version number out of paket.dependencies and deleting all paket.exe files from AppData\Local\NuGet\Cache\Paket. (I know, I really need to get out of the habit of applying two "fixes" at once so I can pinpoint these things better!)
