Discover up date won't work?

[GregM]

Discover said I have updates and I tried to run it as I usually do but I goth this message.....

Cannot obtain lock:

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

Tried to run some commands in Terminal but nothing worked.
Is there a command that I can run that will fix this?

Thanks

PS
The wife's 22.04 computer is getting the same message.

This seems to be happening. I opened Synaptic, and then Edit > Fix broken packages. Also clicked Check for updates. Somehow -- somehow -- that fixed mine recently. It was a little unclear to me exactly what I did.

But, the guys here usually say to try this:

sudo apt update && sudo apt full-upgrade.
sudo apt-get update
then
sudo apt-get upgrade
then
sudo apt-get dist-upgrade

If Discover freezes, then rather than a hard re-boot, you can kill it by,
ctril-alt-esc

[Qqmike]

Those are the older version of the apt command, which still work.
apt-get update refreshes the package list from the repositories.
apt-get upgrade installs newest versions of all installed packages.
apt-get dist-upgrade performs the function of upgrade, but also smartly handles changing dependencies with new versions of packages.

I tried your suggestion about opening Synaptic and it would not open.

Have you tried rebooting and then running the commands?

[GregM]

I tried
sudo apt -f install a couple of times

It seemed to work and then I did

sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove --purge

and it seems to be working now?

So I backed up my 22.04 disk and then tried to do the 24.04 update from Discover and it failed.
A little box came up and said it failed for the following reasons...... but it was blank.

[GregM]

Well I kept at it and finally 24.04 started updating.
It finished but a few things no longer work Like Synaptic.
Some sudo commands in Terminal don't work.
Spectacle doesn't work

It says I have 24.04 but what a mess
