Disk partition full

[Jorhel]

Hi,
Before to do a clean install of 16.04LTS I created partition on my disk following advice somewhere that it is a good thing to do.
Last time I tried to upload a batch of photos from my camera it told me not enough space so I ran df which returned

Filesystem 1K-blocks Used Available Use% Mounted on
udev 746876 0 746876 0% /dev

tmpfs 154184 52 154132 1% /run/user/1000


telling me that my home disk partition is full.
So my question is how do I save stuff in the other part of the disk?

It looks like you have a very large / (root) and very small /home?
And most desktops do not need a separate /boot. If LVM or full disk encryption it often has a separate /boot.

I use 25GB for / but have all my data in a large data partition. But I have multiple installs for testing or next version and want same data, but not necessarily same configurations, so do not have separate /home.

Because I only use 25GB for / I have many 25 GB partitions. I have 16.04 as main working install, but just reused my old 14.04 working install as a new 18.04. But will probably reinstall 18.04 once released. Just testing it now. And I have a couple of other installs to experment with settings as I do not want to corrupt my main working install.

I do back up all of /home regularly, some settings, and list of installed apps, so I can restore working install if necessary. I separately backup my data partition.

Some of the versions have now changed. Note that drive is not fully allocated, or room for more 25GB / partitions or data.

You have a strange partition setup. Generally, if there is a separate /home (or for some users, data) partition, it will be by far the largest partition as it should be. Your df output shows a boot partition which is 2 1/2 times the size of the /home partition. As pointed out above, a separate boot partition generally isn't needed unless you are using LVM and I rarely see a boot partition larger than 500MB.

What you could do is create a directory for your photos on the / (root filesystem) partition as there is a lot of space there. YOu would need to do this as root (using sudo) and then give your general user(s) read/write permissions to that directory or directories.

Thanks for all the links, I'll need a long sit down and think to make sense of it all or more than likely of some of it... The strange setting come from not being sure how much was needed where when I created the partition. Is there a way to just resize the partitions without breaking everything? I used gparted to do it under xubuntu 14.04 before to install 16.04. tried to install them side by side but never worked.

You have to use live installer as partitions you edit cannot be mounted. You still often have to swap-off or unmount swap as live installer will use it if found.

But it depends on where partitions are and how much data.
If expanding right into unallocated space, it can be quick.
Do not queue steps but run each one.
If lots of data it can be a very slow process to move that data, never interrupt it or you lose all data.
Be sure to have good backups.
