I have installed go 1.7 in Debian to make doh
It has a Makefile, which triggers the download and install of dependencies into my GOPATH.
The net package is there:
$ ls $GOPATH/src/github.com/golang/net/
AUTHORS context dict http idna ipv6 lif PATENTS README.md webdav
bpf CONTRIBUTING.md dns http2 internal lex nettest proxy route websocket
codereview.cfg CONTRIBUTORS html icmp ipv4 LICENSE netutil publicsuffix trace xsrftoken
Yet during the build, it says it cannot find net.Resolver
$ make
go get -d -v ./doh-client ./doh-server
cd doh-client && go build
# _/home/share/apps/dns-over-https/doh-client
./client.go:47: undefined: net.Resolver
Makefile:46: recipe for target 'doh-client/doh-client' failed
make: *** [doh-client/doh-client] Error 2
This is my first go with go, so I am not sure how it goes about pulling in imports, and whether the Resolver part is present.

Check your IPv4 address with the ipconfig command
Open webpro/conf/app.conf and paste the IPv4 address into the http.addr parameter
I'm having problem while vendoring my go-project. Tried with both glide and go-dep - getting same problem.
$ go get -u go.opencensus.io gives the following error:
package go.opencensus.io/opencensus-go: unrecognized import path "go.opencensus.io/opencensus-go" (https fetch: Get https://go.opencensus.io/opencensus-go?go-get=1: dial tcp <some-ip>: i/o timeout)
Github link of this package - https://github.com/census-instrumentation/opencensus-go
Tried setting a proxy to shell
export http_proxy=http://104.248.231.49:8080/
export https_proxy=http://104.248.231.49:8080/
And then it worked.
I have generated a Yocto image to be used on all my target devices. When that image is running on target devices, it must be able to be updated using a rpm remote repository through https protocol.
To try doing that, I have added a dnf bbappend to my custom layer:
$ cat recipes-devtools/dnf/dnf_%.bbappend
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI += " \
file://yocto-adv-rpm.repo \
"
do_install_append () {
install -d ${D}/etc/yum.repos.d
install -m 0600 ${WORKDIR}/yocto-adv-rpm.repo ${D}/etc/yum.repos.d/yocto-adv-rpm.repo
}
FILES_${PN} += "/etc/yum.repos.d"
This is the content of repository configuration file included by dnf bbappend recipe:
$ cat recipes-devtools/dnf/files/yocto-adv-rpm.repo
[yocto-adv-rpm]
name=Rocko Yocto Repo
baseurl=https://storage.googleapis.com/my_repo/
gpgkey=https://storage.googleapis.com/my_repo/PACKAGEFEED-GPG-KEY-rocko
enabled=1
gpgcheck=1
This repository configuration breaks the build process of the image. When I try to build myimage recipe, I always get this error:
ERROR: myimage-1.0-r0 do_rootfs: [log_check] myimage: found 1 error message in the logfile:
[log_check] Failed to synchronize cache for repo 'yocto-adv-rpm', disabling.
ERROR: myimage-1.0-r0 do_rootfs: Function failed: do_rootfs
ERROR: Logfile of failure stored in: /home/yocto/yocto/build/tmp/work/machine-poky-linux/myimage/1.0-r0/temp/log.do_rootfs.731
ERROR: Task (/home/yocto/yocto/sources/meta-mylayer/recipes-images/myimage.bb:do_rootfs) failed with exit code '1'
However, when I replace the "https" by "http" in "baseurl" variable:
baseurl=http://storage.googleapis.com/my_repo/
Then the myimage recipe is built fine.
The host machine can download files from the https repository using wget:
$ wget https://storage.googleapis.com/my_repo/PACKAGEFEED-GPG-KEY-rocko
Previous commands works fine, so the problem is not related with the host machine, I think it must be something related with google certificates and yocto stuff.
I found some relevant information inside this file:
yocto/build/tmp/work/machine-poky-linux/myimage/1.0-r0/temp/dnf.librepo.log
The relevant part:
15:56:41 lr_download: Downloading started
15:56:41 check_transfer_statuses: Transfer finished: repodata/repomd.xml (Effective url: https://storage.googleapis.com/my_repo/repodata/repomd.xml)

CApath: none]
15:56:41 lr_yum_download_repomd: repomd.xml download was unsuccessful
Can some of you provide any useful advice to try to fix this?
Thank you in advance for your time! :-)
I finally fixed my issue removing completely my dnf bbappend recipe from my custom layer and adding this variable to my distro.conf file:
PACKAGE_FEED_URIS = "https://storage.googleapis.com/my_repo/"
After that, at the end of the build process the image contains a valid /etc/yum.d/oe-remote-repo file and all the necesary stuff to manage it. There is no need to copy "ca-certificates.crt" manually at all.
Also, it's important to execute this command after finishing the build of the image:
$ bitbake package-index
This command generates a "repodata" directory within the package feed needed by the target device once it uses the repo to update packages using dnf client.
I found a temporal hack to fix my issue:
$ cp /etc/ssl/certs/ca-certificates.crt /home/yocto/yocto/build/tmp/work/x86_64-linux/curl-native/7.54.1-r0/recipe-sysroot-native/etc/ssl/certs/
After that, I was finally able to build the image using the "https" repo.
Now I am in the process of fixing this issue in the right way. I'll come back with the final solution.
So I am trying to install my Go app's dependencies on my Raspberry 3/Raspbian system with "go get" and running into the following when trying to install gRPC for Go:
[pi#raspberrypi-1 camera-service] 17:32:28 % go get google.golang.org/grpc
package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp: lookup google.golang.org on 192.168.1.1:53: read udp 192.168.1.64:33524->192.168.1.1:53: i/o timeout)
Meanwhile I am able to install other (non-google.golang.org) dependencies (for example go get github.com/asaskevich/EventBus) just fine.
To me this looks a DNS problem -- 192.168.1.1 is my router, 192.168.1.64 is my RPi. However I can resolve the address just fine:
[pi#raspberrypi-1 camera-service] 17:32:52 % host google.golang.org
google.golang.org is an alias for golang.org.
golang.org has address 216.58.209.145
golang.org has IPv6 address 2a00:1450:400f:804::2011
golang.org mail is handled by 1 aspmx.l.google.com.
golang.org mail is handled by 2 alt2.aspmx.l.google.com.
golang.org mail is handled by 2 alt1.aspmx.l.google.com.
golang.org mail is handled by 2 alt3.aspmx.l.google.com.
This is weird. Also I have installed the same packages on another system np.
My environment is
- Go 1.8.3, installed from prebuilt ARM6 binary
- export GOROOT="/usr/local/go"
- export GOPATH="/home/pi/go"
This may be because you are using the built in DNS resolver in Go, rather than delegating to the system name resolver. When you built gRPC, did you set CGO_ENABLED=1 ? You can check by setting GODEBUG=netdns=cgo when getting gRPC:
$ GODEBUG=netdns=cgo go get google.golang.org/grpc
# pkg publisher
PUBLISHER TYPE STATUS URI
solaris (preferred) origin online http://pkg.oracle.com/solaris/release/
#
# pkg install gcc-3
pkg: 0/1 catalogs successfully updated:
Unable to contact valid package repository
Encountered the following error(s):
Unable to contact any configured publishers.
This is likely a network configuration problem.
Framework stall:
URL: 'http://pkg.oracle.com/solaris/release'. (happened 4 times)
Found the Answer:
It was adding the proxy settings to profile
export http_proxy=http://URL:port
If you what to use the repository also in the non-globale zone it is better to use the pkg set-publisher --proxy option because the zone pkg proxy does not know your enviroment. Without the proxy option the repository works in globale zone but not in non globale zone.
