when i type this code in the xterminal;

"sudo gainroot

apt-get remove<filename>"

it reads;

'Unable to lock the administration directory (/var/lib/dpkg/),is another process using it?'

Pls what do i do next?

Most probably, you have App Manager open. Close it.

you are a genius,i did close the app manager and i have just removed one application.the last part reads;

"after this operation,119kb disk space will be freed.

Do you want to continue [y/n]?"

so whats the next step?do i remove more app?

well, u have to confirm whether u want to remove or not, that's why it prompts u to enter [y/n]

and try what the 3rd line i suggested too, i'll type it again here:

this command will auto remove any bad packages or packages missing important contents. I.e, invalid ones.

when i entered 'y' it reads;

"dpkgarse error,in file /var/lib/dpkg/available' near line 1435 package 'gstranslate':

EOF during value of field 'Maemo-Icon-26' (missing final newline)

E: sub-process /usr/bin/dpkg returned an error code (2)"


and when i entered this third line,

'apt-get autoremove'

it reads;

"reading package lists....Done

Building dependency tree

Reading state information...Done

Building dependency tree

Reding information...Done

0 upgraded, 0 newly installed,

0 to remove and 76 upgraded".


what do i do next pls?

Quick reply.
/var/lib/dpkg/available is corrupted. I don't know exact solution, but try:

sudo rm /var/lib/dpkg/available
and
apt-get update

and all is good...

And I'm going to say that this is part BS.
I run 64-bit Linux(Mint 8 KDE x86_64 on my laptop, Kubuntu 9.10 x86_64 on my desktop, and just moved to Mint 9 KDE x86_64.
uname -a on my laptop shows:
I have flashed my N900 many times successfully from these.

What I did was:
1. Download the flasher3.5.tar.gz
2. Extract it to a temp directory
3. run "chmod +x flasher-3.5" from that directory, so it can be run.
4. Run it.

Now, I'm willing to bet that the reason it works, when it logically shouldn't, is that I have the ia32 libs installed on my machines. While some may consider this "cheating", as it allows you to run 32-bit excecutables by installing the 32-bit libraries the programs need to run, in this case its perfectly valid - It means you can use your 64-bit Linux OS to run this flasher.
Note though that I didn't manually install the ia32 libs on my new desktop, and I flashed successfully with it, so I dunno - They may have been included in the default packages though.


So, in conclusion, it -IS- possible to use your 64-bit Linux system to flash your N900, and easily too - you may have to install a few packages, though.
