apt fails to install package duo to the lack of space and "read-only filesystem"

A fresh installation of UT 20.04 OTA-7 (Kernel 4.14.188) on top of MIUI 12.0.3.0 (as recommended) on Redmi Note 9S (Curtana) 128G/6G model starts with

I can see that '/' is full, what why would this happen on a fresh installation of UT?
The adage: "Nothing in life is easy. But if it is too hard, you are probably doing it wrong." comes to mind here.
You are trying to use apt (to install / update) on UT. UT is set up as an immutable distro. As such the root filesystem is read-only and updates are provided as delta's to the previously expected state of the system. Because of this, it is not necessary for there to be much free space in the / partition, which is read-only anyway. In consequence
aptis not supported, neither is making the / partition read/write.Packages that are installed from the Open Store are installed in /userdata, which as you can see does have ample free space. You could tweak apt to install to the writeable area too. One such initiative is Crackle. Search for that in the forums for more info. It doesn't make everything work as yet, but you might want to contribute to the effort.
Another option, depending on what it is you need to install, is to create a Libertine container (also search for that).
Be advised that as a rule, services do not run in a Libertine container, but can be made to work with Crackle.
An up and coming option is to run snaps. On 20.04 they have to be enabled with the Snapz0r app from the Open Store, which also requires certain features to be available in your devices kernel.
Current limitations with snaps are: Not all GUI apps work, and of those that do, there is no native OSK support.
-
@arubislander why though? I've tested some CLI and GUI apps from apt and they worked just I expected (aside from scaling), it wouldn't be much to shrink /userdata 10-20 GiB and expand the / partition with it.
How easy is it to do that? Because they seem to be configured and partitioned in an awkward way (to me). Can you help me with it? -

@arubislander why though?
Because UT aims to be Mobile Linux for Human Beings.
I've tested some CLI and GUI apps from apt and they worked just I expected (aside from scaling),
In that case, these apps would also run in a Libertine container. Please look into that option.
it wouldn't be much to shrink /userdata 10-20 GiB and expand the / partition with it.
How easy is it to do that? Because they seem to be configured and partitioned in an awkward way (to me).Maybe. I don't know. I know that existing android partitions are reused and repurposed. I am not sure if any additional partitions are made, or that these are all vendor determined. (maybe the layout needs to be just so, so that "vendor blobs" function?). Anyhow, the way things are laid out differs from device to device, and is determined in large part by the porter of the device.
Can you help me with it?
I am no expert in this area. So I cannot help you with resizing partitions. The only device I have successfully fiddled with the partitions on was the Meizu Pro 5. Since then I have found that respecting the philosophy of the OS, and finding ways to do what I need within those confines, works better in the long run.

Hi @linux_dude
The partition size is fixed on Ubuntu touch.
There is no debate about it.I use to say that if you cannot work around those limitations, you shouldn't do it at risk of damaging your system.
Ubuntu Touch has an immutable filesystem for consistency across devices, stability, and ease of use and maintainability.If you want to install desktop apps on your device, the beta version of what is supported are snaps.
You can use snapz0r from the open-store to enable it on your device.
You can also use Libertine like @arubislander already mentioned.
