u14.04 warning /var only 46MB remaining. /var is 1GB cache 75% What do I delete?

[nu2u904]

Used gparted to shrink xp drive by 2/3, gave 1/2 to xp leaving 140GB for u14.04; set up partitions for / 25GB, /home 20 GB, /var 1GB, /usr/ 20GB , /tmp 1 GB;free 70GB . Only / is a physical partition. I understood I only needed max .5GB for /var. How can I expand /var.? What files in /var/cache can I delete. This is fresh install and there are no old packages? How do I recognize a package? How critical is this warning? xp is currently unbootable error msg: missing or corrupted file: C:windows\system32\config\system? Can I access this file from u14.04 and replace it with another copy?

632M /var/cache


sudo apt-get autoclean

That should do it, but I still think your /var needs to be larger.

Thank you. I agree. What are the steps that I must take to increase /var. I have 70GB of unallocated space following the u14.04 partitions? What size should I make /var?

I attempted update sw and response was I was 59MB shy. I did a sudo apt-get clean . I then successfully downloaded 159MB of updated packages. This is /var before the update and then after:

After clean

why do you need a separate /var anyway? or for that matter so many separate (and small) partitions... to me it seems this is just asking for low space problems...

second questions - yes that should be possible if that is really a solution.

I agree, the default configuration works well for me.

[nu2u904]

I agree. So now how do I return Var to Root / where it can expand to the limit 20GB I allocated to root. Root is on physical partition /dev/sda3.
Do you also believe that /boot should not be on its own very small partiton?

[ibjsb4]

Why not just reinstall and use the default settings?

[nu2u904]

I down loaded a lot of packages. What happens on a reinstall? If var is in / does it auto expand as the nee arises; / is 25GB? How can I move /var into root? Or how do I expand /var?

Easy :) Create a "markings list" using Synaptic-package-manager. This will reinstall all packages with just a few clicks.

I have never ran out of space.

sudo apt-get install synaptic
