I corrupted my ubuntu 18.04 network files and now not only does the boot hang, with the consistent
FAILED to start RAISE Network Interfaces
but i also cannot run repair options/update && upgrade through the grub menu tty
I have spent days following many threads, starting from simple sudo ifup eth0 up, to changing many settings in files for NetworkManager through /etc/network/interfaces and networkd through /etc/netplan/01-netcfg.yaml and all the trappings of those rabbit holes.. i'm sure it looks like swiss cheese in there!
Currently, I have dual-boot..
Ubuntu 18.04, and have tried both my current kernal and its depreciated backup kernal, and their recovery mode kernals
Windows 8, which I am using now so no hardware issues (but maybe bad-block/corrupted/degraded disk which the boot is written to..?) ..and
networking through wifi only, from which Windows allowed me to make a working live usb 18.04
Boot-repair is available for those still within their running (corrupted boot/networking) OS, but for those like myself who cannot boot their kernel... and no network in the kernal or respective recovery mode, so no access to repair/apt-get update etc..
is there a way to transfer networking and/or boot files to a corrupted OS (iso) within the recovery mode tty (accessed through grub menu) so that update && upgrade can be run?
