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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1542252 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.
