I have an old Compaq nx7000 work laptop that I have Ubuntu on.
sudo do-release-upgrade -d # It's before the official release date of Ubuntu 10.04 so I ran with the -d switch # -d, --devel-release Check if upgrading to the latest devel release is # possible
and got a complaint back that I didn’t have enough disk space. I had 1.4GB free on the root (/) partition and it needed 2.2GB to do the upgrade.
Tried the usual process of removing old packages & cleaning up:
sudo apt-get clean sudo apt-get autoclean
I even ran the System ==> Administration ==> Computer Janitor utility however these steps didn’t claw enough space back.
Analysing my space available using df showed that I didn’t have enough spare space on my root partition but /home had plenty of spare space
df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 5.5G 3.9G 1.4G 75% / none 371M 280K 371M 1% /dev none 375M 192K 375M 1% /dev/shm none 375M 196K 375M 1% /var/run none 375M 0 375M 0% /var/lock none 375M 0 375M 0% /lib/init/rw /dev/sda6 22G 4.5G 16G 22% /home
The work around:
I went into /usr and had a look at the space being taken up by the /usr/* directories and discovered that /usr/share was a good candidate for moving to another volume.
# go into /usr cd /usr/ # preface these commands with sudo # check the disk usage du -sh ./* 207M ./bin 2.0M ./games 26M ./include 1.3G ./lib 92K ./lib64 3.8M ./local 21M ./sbin 1.9G ./share 28K ./shareFeisty 238M ./src # identify that /usr/share is a good candidate to move to another partition with more space on it # copy it # -a preserves the permissions and ownership # -r copy's subdirectories # -v just shows you what files cp is currently copying cp -arv /usr/share /home # mv the old /usr/share and then link it to the new location mv /usr/share /usr/share.old ln -sf /home/share /usr/share # oh and you need to remove the share.old # directory to actually get the diskspace back rm -rf /usr/share.old # run the upgrade
After the upgrade:
The only problem with leaving the system this way is that some of the links in /usr/share point to relative paths so may get confused. I noticed this because my firefox desktop icon broke.
So I reverted back to the original layout after the upgrade completed:
Reverting back to the default /usr/share configuration
sudo apt-get clean sudo apt-get autoclean # make sure you check that you have enough # space to revert! sudo df -h sudo du -sh /home/share # when you now it's all ok do the following cd /usr # when you remove the share link you will lose your desktop icons because they can't find /usr/share/* # The network manager applet will also quite # complaining "could not find some of it's required resources" sudo rm share sudo cp -arv /home/share ./ # after you finish the cp command reboot to make sure it's alright.
