Could you cut and paste what happens in the terminal, please?

Put the text between code tags by clicking the "#" symbol above the input box when you post back.

give a try as this

after getting the login screen Press CTRL+ALT+F1 and Login.Then type as this


sudo dpkg --configure -a

give us the error report if anything you got .

Yeah,tried it error is invalid command:



E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.




bryan@bryan-Extensa-4420:~$ dpkg-configure-a
dpkg-configure-a: command not found
bryan@bryan-Extensa-4420:~$
this is what happens when i run this command???
and this is what happens when i run package mgr
Software index is broken

It is impossible to install or remove any software. Please use the package manager "Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first.


bryan@bryan-Extensa-4420:~$ sudo apt-get install-f

(Ed. Moved my question to a new thread)

I don't know if it's appropriate to piggyback on this thread or start a new one. I too had an upgrade failure from 11.10 to 12.04, but it wasn't due to a power failure. The system comes up with a login screen. The splash screen says 11.10. When I try to login, it looks like it accepts my password and then immediately logs me out.

I tried booting from a LiveCD because another thread indicated there would be a repair upgrade command, but I don't see that. It tells me 12.04 is already installed.

I ran the command suggested above,

sudo dpkg --configure -a

after logging on to a recovery session and it tells me,

"dpkg: error: parsing file '/var/lib/status' near line 21798 package 'xmind' : blank line in value of field 'Description'"

But, I don't know what to do about it. Edit it with vi and delete the blank line?

It's not considered polite to hijack someone else's thread because it confuses things. You'll get more action in your own thread. But the staff may balk at a repeat post, so edit your post above to say something like "Moved my question to a new thread"
