./scripts/install fail

[efa]

you should list all the dependancies for the software.
With try and error I found at least:
$ sudo apt install golang golang-github-mattn-go-sqlite3-dev golang-github-beevik-etree-dev

Now running
./scripts/install
I got this error:

../../gpx.go:8:2: cannot find package "github.com/beevik/etree" in any of:
	/usr/lib/go-1.11/src/github.com/beevik/etree (from $GOROOT)
	/home/efa/go/src/github.com/beevik/etree (from $GOPATH)

the etree package is installed.
These two env vars are undefined in golang 1.11
Debian10

as default I had
GO111MODULE=auto
setting:
export GO111MODULE="on"
solved the install

is there an alternative method to "Huawei Backup App" for user of other brand of mobiles (Backup App doesn't install)?
