apt-get: You don't have enough free space

[Lukas1]

Hi,

I installed node.js with apt-get on my STM32MP157C-DK2, which worked great.

Now I want to install another package but it fails

apt-get install nodejs-npm

...
Need to get 7286 kB of archives.
After this operation, 0 B of additional disk space will be used.
E: You don't have enough free space in /var/cache/apt/archives/.

But I think there is still enough free space on the SD Card:

root@stm32mp1:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root       715M  682M     0 100% /
devtmpfs        150M     0  150M   0% /dev
tmpfs           214M     0  214M   0% /dev/shm
tmpfs           214M   20M  195M  10% /run
tmpfs           214M     0  214M   0% /sys/fs/cgroup
tmpfs           214M  4.0K  214M   1% /tmp
/dev/mmcblk0p4   58M  8.5M   46M  16% /boot
tmpfs           214M   80K  214M   1% /var/volatile
/dev/mmcblk0p7   14G   74M   13G   1% /usr/local
/dev/mmcblk0p5   15M  8.4M  5.1M  63% /vendor

hope someone can help. Otherwise I have to cancel my work with node.js

regards

Hi @Lukas​ 

Your rootfs is full.

Please note in section https://wiki.st.com/stm32mpu/wiki/Package_repository_for_OpenSTLinux_distribution#Limitations

rootfs available space is about 60MB by default. For a better experience it is recommended to flash the Starter Package using the "extensible" flashlayout (*-extensible.tsv).

Extensible flashlayout does not flash userfs partition to extend the rootfs partition to the size of the sdcard.

Hi @Community member​ ,

thanks for your fast reply.

I want to avoid flashing a new image. Is it possible to expand rootfs on the installed image?

Hi,

you can't resize a mounted partition, as far as I know.

What you can do is take your SD-Card and mount it on a seperate Linux PC. There you can then unmount it and use tools like gparted or fdisk to resize your partition.

Bare in mind, that this is (again as far as I know) just possible if there is no other partition on a higher offset than your rootfs. From your listing i assume that that is the case and the vendor filesystem resides at a higher offset than the rootfs (the rootfs should be on /dev/mmcblk0p6).

If that is the case deleting the vendorfs might help you.

Hi,

I moved /var/cache/apt to /usr/local and created a symbolic link. Works for now, but I don't think it's a permanent solution

Hi @Community member​ 

On trying to extend rootfs to the entire sdcard, I tried to flash the extensible flashlayout to my MPU157-DK2 board. I am using the Distribution Package.

I did not get the entire SD Card memory to be used but rather something below 1GB.

Are there any options that I am missing to extend the rootfs?

Hi,

I fixed after image creation by using the following command on a Linux machine. sdb6 is the rootfs partition when created with the extensible flashlayout.

sudo resize2fs /dev/sdb6

Of course this only works after image creation.
