I was trying to install Ubuntu OS on my Nexus 4, everything downloaded just fine. After that it started booting into boot.img and that's where the issues started. Here's what I got on screen:

INFO:phablet-flash:Booting /tmp/tmpbT_cJ5/partitions/recovery.img
downloading 'boot.img'...
OKAY [  1.085s]
OKAY [  0.004s]
finished. total time: 1.088s
INFO:phablet-flash:Waiting for install to finish on device. Please do not unplug device until phablet-flash finishes.
ERROR:phablet-flash:Installation is taking too long or an error occured along the way.
Removing directory /tmp/tmpbT_cJ5
Removing directory /tmp/tmpsMhqAw

Before installation failed the screen was black for around 10 minutes on my phone. I can boot into bootloader and recovery mode but I don't know what to do to either finish installing Ubuntu or to revert to Android 4.3.

Could this be connected to your USB port? On my laptop I have two USB ports. Connecting to my nexus4 and flashing ubuntu-touch only works from the "older" USB port, the other one (with USB power) is less reliable. –  Joachim Van der Auwera Sep 26 '14 at 11:51
