How to install go 1.8 on Ubuntu 16.04

If install golang in Ubuntu 16.04 throught synaptic, you will install version 1.6 and maybe you will see the following problems:

cannot find package "golang.org/x/sync/errgroup" in any of:
/usr/lib/go-1.6/src/golang.org/x/sync/errgroup (from $GOROOT)
/src/golang.org/x/sync/errgroup (from $GOPATH)
exit status 1
exit status 1

To avoid it, is better install it from the source:

wget https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz
sudo tar -zxvf go1.8.linux-amd64.tar.gz -C /usr/local/
mkdir ~/go
echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
echo 'export GOPATH=$HOME/go' >> ~/.bashrc
echo 'export PATH=$PATH:$GOROOT/bin:$GOPATH/bin' >> ~/.bashrc
source ~/.bashrc

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing.
