How can I repair a broken F15 installation without undertaking a clean install? I'll spare the convoluted and confusing details of how I arrived at this junction in favor of disclosing that my problem began when I attempted to correct an error that was returned by the automatic system update. The system would not accept an update for the kernel? For a few weeks I got by without undertaking updates of any kind, as the app was broken for all intents and purposes. Any time I would initiate an update, the app kept barking about the last transaction failing to complete. Last night I removed a bunch of packages that were identified as problematic and here I am. Now the system does not completely boot. I get a boot splash but there aren't any processes running behind it, nor does the fedora "bubble" completely fill: the last tiny sliver remains grey. Escape returns the process message "sh: cannot set terminal process group (-1): inappropriate ioctl for device" at that point.
Thankfully I have a liveusb image from which I can boot. I made one earlier on another system that was down until I made repairs. So, I can rescue my files from the problem system as a last resort, but my hope is for repairing the instance currently installed. Is there something I can do from within liveuser environment? I tried to install some missing stuff using yum earlier. Everything looked fine right up until the end, when the process stopped with an Errno5 message. Something about a input/output error. I'm very new to using Linux so I'm sure I didn't do something right. Perhaps the files weren't directed to the local HDD, but to the usb stick from which I booted?
As an aside, finding the apps installed on my workstation has taken some time and would be difficult to reproduce from memory. Just the same, if some one could share the command to use so that all the installed programs are listed in CLI, I'd appreciate it.
Is there any hope?
