Conan download failures


Perhaps similar to this answer, but I am experiencing a difference in conan download between Conan proxy and hosted repositories.

For proxy repos, if I execute the command conan download -r=conan-center openssl/1.1.1g@ the recipe and all compiled binaries hosted on Conan Center are downloaded to my local cache.

For hosted repos, if I execute a similar command for an application and binaries we’ve built and uploaded to our hosted repository, I get the following output:

% conan download -r=conan-dev-hosted Application/0.0.1@user/channel
Downloading conanmanifest.txt completed [0.06k]                                          
Downloading completed [1.62k]                                               
Application/0.0.1@ user/channel: Getting the complete package list from 'Application/0.0.1@ user/channel#0'...
ERROR: 404: Not Found. [Remote: conan-dev-hosted]

Because of our particular needs, I’m scripting Conan’s download and upload commands to export and import our Conan application packages (recipes and compiled binaries) between repositories. This is a critical function for our development environment.

Can anyone tell me if downloading “packages” from Nexus Conan hosted repositories is supported?

Hello @austin
So you are downloading some libs from conan-center and push them into your NXRM conan-hosted repo? And after you can’t fetch binaries from hosted. Did I understand problem correct?
If yes, conan upload command does not upload packages by default, it uploads only recipe. To Upload recipe and packages you need use --all flag

Hello @iudovika,

We are using the --all flag and I can see the packages folders in the web GUI for the application/version@user/channel. I’ve attached a screenshot. When I do conan download..., I get the recipe in 0.1-test, but I cannot download any of the packages folders. I was under the impression that these packages contain all of the binaries we built for our target architectures, which is what I need in my other repository to use as dependencies when building our applications. The second repository is not connected to the internet so recipes in it cannot fetch source code to compile binaries.

Thanks, I will try to have a look on code base and will update you if will find the reason of such issue.

Hello @austin
I made investigation and seems you where right. conan dowload command works via search engine that still is not implemented in hosted repo.
