Hi
I want to start a small server, that will be accessible form outside. Not a huge deal right?
Not quite.

My machine: 4.15.0-66-generic #75-Ubuntu SMP Tue Oct 1 05:24:09 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Now, I try to install dub from the official repo.
Then I do

* dub init server -t vibe.d
* cd server
* dub

I hit this issue : https://github.com/dlang/dub/issues/1712

As suggested, i try to build dub from github, following: https://github.com/dlang/dub/releases

I call ./build.d - and everything stops, and machine crashes.

I then try to install DaNode: https://github.com/DannyArends/DaNode

It breaks with : module std.algorithm import 'mean' not found

Then I try to install the Hunt Framework. It breaks with : basic type
expected, not foreach


Please help. I really want this issue to be resolved-

I don't know if it is a solution. But you can try using ~master branch, not a release on GitHub.


You can also try my vibed app skeleton:
https://github.com/aferust/simplerestvibed
İ simply run it with dub command.

I even tried:

$ dub fetch dub

Please note that you need to use `dub run <pkgname>` or add it to dependencies of your package to actually use/run it. dub does not do actual installation of packages outside of its own ecosystem.

How is your network connection to the dub server? Maybe there is a separate problem with network connectivity.

This thing works for me (dub upgrade takes about 2.5 seconds and finishes). How long does it take for your process to give up?

In any case, maybe the dub check to see if it's "taking too long" needs to take into account progress that is being made (a "pathalogical case" suggests it's not making progress).

What version of dub did you install? 1.19 should be the latest.

With dub 1.18 more than 5 minutes.

If i use dub search dub, it finishes in seconds.

dub fetch dub is fine too.

dub run dub takes 10-12 seconds, and throws the same dependency error
