Cannot run golang snap as a non-root user

snap

I may miss something here. I installed the go snap by a root user.

snap install --classic go

Then after I switched to a normal user, say ubuntu, it cannot launch the go program as the root did.

Here is what root user see:

root@v1:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
root@v1:~# go version
go version go1.9 linux/amd64
root@v1:~# go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/go"
GORACE=""
GOROOT="/snap/go/727"
GOTOOLDIR="/snap/go/727/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"

And here is what ubuntu user see:

ubuntu@v1:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
ubuntu@v1:~$ go version
The program 'go' is currently not installed. To run 'go' please ask your administrator to install the package 'golang-go'
ubuntu@v1:~$ go env
The program 'go' is currently not installed. To run 'go' please ask your administrator to install the package 'golang-go'

However, the ubuntu user can launch the go program by specify the path:

ubuntu@v1:~$ /snap/bin/go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/ubuntu/go"
GORACE=""
GOROOT="/snap/go/727"
GOTOOLDIR="/snap/go/727/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
ubuntu@v1:~$ /snap/bin/go version
go version go1.9 linux/amd64

What am I missing? Should I manually put /snap/bin to /etc/profile so every user on the system can use the go snap?

How was that ubuntu install created ? normally snapd puts a profile.d snippet in place to extend your PATH for a user…

That said, if you did not have snapd installed before, you need to log out and back in after installing it to make the profile change take effect.

Thank you for the reply.

The hint of /etc/profile.d/apps-bin-path.sh really helped me here. I simply su ubuntu to tested the result :joy_cat:, which should be su -l ubuntu, so the /etc/profile.d/* are not sourced.

It’s my bad. Thank you. :smiley_cat:
