Comment 3 for bug 1693754

Hello!

First of all, thank you for your answer; en please escuse my english.

Second: my real problem was tu install a wifi driver for my lenovo B590
(broadcom wifi card).

I also realise that the graphic interface was blocked with an update.
Unable to progress. I push "Install" and nothing. Severels times reboot and
still nothing, for severals days.

Today, I found a solution on the ubuntu support forum. (after writing to
you). I cann't find the exact page. But I copy/paste the commands in
terminal. This unblocked the situation:

sudo apt update

sudo apt-get update && sudo apt-get -y autoremove && sudo apt-get -y upgrade

cd /var/lib/apt/lists && sudo rm -rf lock

cd /var/lib/dpkg && sudo rm -rf lock

I'm not un super user of linux. I'm not sure if this is the best solution,
but it worked. Update is ok ans I was able to install the wifi driver withe
terminal. Later, I was able to install also "Synaptic".

Thank you for your help.
