Booted Previous version

[theller]

somewhere along the way, when I started the computer I chose to run a previous version, probably after a failed update. Since then I have added many users. Last week I restarded the computer and chose the current kernel and the users were gone and the more recently added programs were gone. I restarted, chose previous version, chose kernel 48 and everything was fine.

How can I make this previous version the current working version? Do I simply run updates or will that update the version I am not using?

My thought is to delete all the other newer versions, restart, then update.

Many posts suggested using Tweak to remove older kernels. Is that what I should use or does anyone have a better suggestion.

Install Synaptic and select from there all the packages of the kernel you want uninstall. (linux-image and linux-headers. Look for it and take your time to select the right one)
After that do a update and upgrade via the terminal.

sudo apt-get update && sudo apt-get upgrade

Thanks for the quick reply.

Will upgrade change me from 12.04 to 13.04?

[heir4c]

No, update is just to renew the packageLIST. Upgrade install effective the new package, but do not a dist-upgrade.
So, if the list is: 1 2 3 4 5 and the new one is: 1 2 4 5 6 than 3 is to be removed and 6 to be add to the list. But the real files of 3 are not removed and the files of 6 are not adding. That do you by using the upgrade option.

Moving from 12.04 to 13.04 is not possible. If you want to do it you must do first a dist upgrade to 12.10 and than to 13.04.
What can is to move from 12.04 to 14.04 next year because there are both LTS versions.

Also, after you remove the linux kernel versions do a grub update:

sudo update-grub

With that you remove the kernel from the grublist.

Thanks for your help. I am going to try this later today. I'll post how it turns out, hopefully I will click solved!

I think it worked. On a restart it went directly to the right version. I did not run update-grub. Does a restart update the grub?

When the system installs a new kernel it automatically runs update-grub.

This is the normal behaviour. Not sure what happened in your case but running the updates seems to have sorted it for you.

I'm glad it work. Hopefully it remains so.

Updates installed a new kernel, that's why the grub was updated.

Thanks again!
