Repairing NetworkManager on Linpus (Acer Aspire One ZG5)
 
Boo!

I have decided to go against good advice and install some updates to my wife's Aspire One, without checking they'd be properly compatible with Linpus (the host OS)...

Suffice to say, eventually I hit a dud, and NetworkManager "has to close". Never to repopen. Now all cabled internet-fuctionality is dead, and I have no local wireless connection to speak of. I started work to fix this epic fail at about five PM, it's now well past one in the AM, and I'm choosing a professional to take this to tomorrow. That is if I can't find a copy of Linpus to burn to disk (I'm not sure if it exists! I do have the complete source though).

In case any of you good people have any better (cheaper) ideas, here's how it went down:

[EOF]

At some point the clearly epic error message (in judgement?) happened after the NetworkManager was being updated and changed. Strange, but true. I have tried to "put things back", but that hasn't had the desired effect (see the log).

I would reinstall NetworkManager but I have no RPM to work off, and no RPMBuild to create one (found two different versions, both fail the installer - one's incompatible, the other doesn't pass the dependency check). Yes, the USB ports work fine. I've even managed to update Firefox which also got taken out in the... Mistake... Would click the relevant icon, nothing happens.

And to think: I didn't even know there was a backup utility!

Suggestions (I will already be hanging my head in shame)?

Have you an open network, or your wpa key? Do it manually (as root).
modprobe <your-wifi-modules> e.g. modprobe ssb && modprobe b43 for broadcom
fix /etc/wpa_supplicant.conf - make sure your key is in there. That's done with wpa_passphrase. read man wpa_passphrase
ifconfig wlan0 up
iwlist wlan0 scan |less
Pick out your router. Note the ssid and run the mouse over your router's mac address e.g. 00:11:33:33:44:55
wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -i wlan0 -Dwext -B &&
iwconfig wlan0 essid your_ssid ap <paste the mac address you gathered above>
dhcpcd wlan0 or mebbe dhclient wlan0

As for hanging the head in shame, not one of us hasn't been there too, sometime. You never make an omlette without breaking eggs.

If you have an AOA110 or AOA150, the version of Linpus used on those machines was based on Fedora 8. You might be able to use the NetworkManager rpms at http://mirror.steadfast.net/fedora//...6/os/Packages/

If both the above and business_kid's suggestion don't work, I keep a copy of the Linpus restore image for the ZG5(AOA110 and AOA150) at http://deli.no-ip.org/aa1. You'll need to uncompress the image file and dd it to a 4GB USB flash drive. WARNING: It'll wipe your Aspire One's drive, so back up any important data before using.

Awesome, awesome, awesome!

Thanks for the link! Any and all are very, very much appreciated! As (I think) I wrote, I got nowhere with the DLs I found previously. In the end I haven't had time to find a pro'(no Linux dev's-for-hire are advertising themselves near me) so this new information is very useful!

I did eventually get a response from Linpus' support peeps, keep reading for a copy of the message...

As business_kid's instructions dictate, his are for manually editing wireless-connectivity conf' files. Unfortunately, I have no wireless in my home (where the machine lives), open or otherwise. I will be keeping his comments on record!

Again: many thanks! Any copy of the restore disk would be greatly appreciated: sadly this machine never came with one... :(
I infer from your writing that this is ready-made from the utility available on any Linpus recovery-disk?
I will be trying to find an RPM first anyway.

And yes, I have now have data-backups!

This is what Linpus sent me two days ago, from my original message sent on the 23rd (near the "day of destruction"):

Many, many thanks, again! I've left a lengthy comment on the Acer Guy link with separate instructions. The tut's good, but you need a Recovery disk to make the USB-ready image from :(

RockDoctor 08-02-2010 06:08 PM

My copy of the recovery image came from a link posted in the forum two years ago, back when I first bought my Aspire One. I didn't note the source, but I did try it out. It worked as it was supposed to; I just didn't care for it. I keep the image up for those who are happy with Linpus, but for some reason need to reinstall. I never had decent luck trying to download the image from the Linpus site.

GrubbySeismic 08-03-2010 05:03 AM

...and I would be lost without it!

I tried getting the .RPMs you listed to install, but the glib pack's missing a dependency "libnm-util.so.0". Oh well. Time to make me an image!

"dd" is a command I'm not familiar with (I'm mostly a graphical lad - strange no?). I'll look it up.
