Most recently, after a few notified updates of my computer I tried to
install Network Manager, just out of curiosity. Surprise-surprise, this
time the system did not complain after reboot. Then I restored
/etc/network/interfaces file to its minimum
auto lo
iface lo inet loopback
and now the system works as before this bug showed up its ugly face.
Network Managers works again.
I don't know what happened, how it happened, but I thought I'd let
developers know.
N.B. When I lost my networking and Internet access I completely purged
Network Manager and set up /etc/network/interfaces file so that I can
use sudo ifup method - see initial bug description above.

Title:
Network unavailable after Libreoffice-5 PPA install
Status in network-manager package in Ubuntu:
New
Bug description:
This bug is a result of solving bug #1454310. After rebooting various
system error messages appeared. Networking was unavailable. According
to one Askubuntu suggestion, removed trusty-security package sources,
apt-get update, upgrade, reinstall network-manager but same problem.
After almost a week's work I was able to reactivate networking via
/etc/network/interface and sudo ifup xxx, first with wired then
finally connecvting to hidden WiFi which I'm using now. If I reinstall
network-manager and its gui companion installation goes well, but at
reboot the same thing happens as described in the beginning. Presently
network-maneger and its gui companion is completely removed. My system
is on an Acer Laptop, 14.04.3 LTS and64, and it has been regularly
updated according to notices. No special or custom programs are
installed or no unusual customization was made.
I'm attaching a file describing what happened a week ago leading to
this system problem.
