Help resizing the root partitiion

[padraic]

Hi,

when trying to install the new browser I ran into a problem with not having enough space in /var/cache/apt/archives

I thought this might have been because I did something foolish with my device (BQ M10 FHD - freiza) but I can see other people having the same problem.

Looking around the forum I can see that people recommend a couple of things:

1. sudo apt autoremove or sudo apt-get clean
2. Resizing the root partition

The solutions in 1. don't free up enough space.

For resizing I can see this script being mentioned - https://github.com/timsueberkrueb/plasma-phone-dev-setup/blob/master/usr/bin/resize-root-partition

Has anyone successfully used it? Is there an alternative?

Is there a recommended size to change to?

Hi @padraic,
to resize the rootfs there is a tool called ATU which can be useful for you at the scope. I can redirect you to the page where there are the steps to be followed and the file to download:

@matteo Hi, I just installed this tool, but I cant press on anything

@padraic @baruchiro @matteo Got the same issue on FP2 and solved it by adding this line to /etc/fstab:

/userdata/system-data//var/cache/apt/archives /var/cache/apt/archives none bind 0 0

Issue then a sudo mount -a and retry installing...

@tera Can you briefly explain what you have done here?

[baruchiro]

@tera I also did not understand if there was a mistake in the characters //?

/userdata/system-data//var/cache

[tera]

@baruchiro Adding this line will allow you to mount that /var/cache/.. folder inside the larger /userdata partition so there is space available to perform the package installation (double slashes are expected, check similar existing lines in /etc/fstab and note it's a bind mount)
Not sure if such change should be made persistant or only considered as a workaround...

@tera It did not work, with the following error:

mount: special device /userdata/system-data//var/cache/apt/archives does not exist

But yesterday I somehow managed to make it work, but then I reinstalled and now I can not.

@baruchiro You may have to create the folders in /userdata/system-data/var/cache/... i do not recall if i did or not on my side

[baruchiro]

Works, Thanks!

You can bind /var/cache/apt/archives temporary, using mount -o bind command.

# create dir in userdata space 
$ sudo mkdir -p /userdata/system-data/var/cache/apt/archives
# mount - bind
$ sudo mount -o bind /userdata/system-data/var/cache/apt/archives /var/cache/apt/archives/

Now your /var/cache/apt/archives has more space until reboot.

This has worked for numerous users: https://forums.ubports.com/post/13645.

I've found running these commands works more reliably from fastboot mode.
