Can't run do-release-upgrade in jaunty to upgrade to karmic Problem executing scripts APT::Update::Pre-Invoke

Asked by doclist

I can't seem to run do-release-upgrade. I get the error attached below. Tried to start debugging it but it was a nightmare with dynamic fetching of the source, indirection and subprocess execution. Apt works fine, I have no apparent network problems.

Also, "sudo daptup --pre" seems to run fine when run from the console and returns a zero exit code.

I accidentally marked this as solved when it wasn't. I'm still having this issue.

ok this is a dead giveaway;

Building old list of packages... errors present. Is apt/dpkg running?

Do you have synaptic or aptitude still running. This will lock the packages and prevent updates.

If you don't then try a reboot. If that doesn't work the run:

sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a

Then try again.

I gave up on do-release-upgrade, resorting to editing sources.list
manually and then doing the upgrade.

I doubt your solution would have worked since aptitude was working
fine otherwise. (I could call it immediately after the failed
do-release-upgrade without problems).

Thanks anyway.

I am experiencing the same problem.
I removed the lockfile, but the problem was still there. ( did run sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a )
