My PC specifications:
- Dell Latitude D830.
Fresh install of Ubuntu 12.04 (64bit) dual boot with windows xp pro 6 days ago.
Chip ID is Broadcom BCM4311.
PCI-ID is [14e4:4312]
Last week I installed Unbutu 12.04 (32bit) on two other old Dell
laptops, an Inspiron 6000 and an Inspiron 9000, with absolutely no
problems. One dual boot and the other on its own.
I am totally new to this, never installed an os before and having
never even seen Ubuntu before last week...so simple answers please :)
This third install went very smoothly, though I had to do it hardwired to the internet, since it couldn't find the wireless: wireless works perfectly in Windows. When restarting after the OS install, the screen got stuck on the Ubuntu logo splash page with the 5 dots. I pressed the button and then rebooted. I have tried all that I could find in this forum on fixes for shutdown or resart, none of them have worked. The screen stays stuck on the Ubuntu with the 5 dots screen and I then push the button to complete the shut down. The last fix I tried was from this link So I've left issue for now and trying to get the wireless working, with no success on the contrary.
I've just installed the bcmwl-kernel-source package from these instructions.
The wireless connection still didn't work, so I shut down and rebooted.
Now after rebooting, there is still no wireless connectivity. The wireless switch on the computer is on. There is still no wireless choices in the menu bar. I decided to run the update manager and it doesn't work anymore.
Not all updates can be installed error with a list of reasons. When I press close, I get another error, this time
Software index is broken, its impossible to install or remove any software - again with suggestions.
I then went and found on the forum how to uninstall what I had just installed through the terminal, hoping to get back to where I started from, since both the update manager and the terminal were working before the install.
The terminal gives me the following result:
sudo apt-get remove bcmwl-kernel-source. Message reads on the Terminal: E: Could not get lock /var/lib/dpkg/lock - open - (11: resources temporarily unavailable) E: Unable to lock the administration directory (var/lib/dpkg ), is another process using it?
Nothing is running in the background.
I'm rather exasperated since every move I make is bran new, and after spending days reading in the forum and trying what seems to work for others nothing does.
Before starting to try to fix the wireless today, everything in Ubuntu works beautifully, now if I can't do updates or use the Terminal, that's not so good.
