I have ubuntu 10.04 installed on my laptop with the following disk organization:
- 20 GB for /
- 5 GB for /home
The large root I have was intended in principle for installing large pieces of scientific software, but in fact I don't have any of that software installed currently. I have checked my disk space for installing ubuntu 12.04 and I have found that it takes ~15 GB. I have checked on the web that a typical installation should be ~4-6 GB.
My question is: how can it be? I don't have big pieces of software, I have also removed the Office Suite to have more space. I keep all my data somewhere else. My installation is pretty minimal. I have already removed all the old kernel and header files, cleaned with
apt-get autoremove and removed any unused piece of software with
In fact I found 4.5GB of scientific software I had forgotten about, nonetheless the installation would be 10.5 GB without those pieces of software, that seems still a lot to me. I also have the full
The upgrade to 12.04 require 5GB of space, and I had to remove 3.5GB of that optional software I had.
Now I have the following:
Filesystem Size Used Avail Use% Mounted on /dev/sda8 20G 15G 4.3G 78% / udev 993M 4.0K 993M 1% /dev tmpfs 401M 860K 400M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1003M 7.0M 996M 1% /run/shm /dev/sda6 5.0G 4.1G 612M 88% /home
that 15GB still look like a lot, it is 3.5GB more than v10.04
