I was installing the TNSR, setting up interfaces, creating a SSHv2 key pair and then I want to update the entire system
(underlying Ubuntu 22.04?) and I was here and there running out of disk space! It was often more the /usr/........ disk space
that was running full and this message was shown more then once;

Failed to write file “/usr/share/glib-2.0/schemas/gschemas.compiled.YHQH21”: write() failed: No space left on device

Is there something like a partition table that could be
right shown with some "let us call it" well known numbers
that I will not running out of space here and there?

I have here an PC Engines APU4D4 with 64 GB Transcend
mSATA, Compex WLE200nx and a miniPCIe GPS card from
uBlox. All will be detected but if it comes to install some packets on top and/or an update, it will be even the same
procedure, running out of space.

So my main question is the following; "How much space may be well for all partitions"?

Perhaps I have some to great and some to small?
Here is the entire table of all partiotions

frank@lankeeper:/$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
NAME   FSTYPE   SIZE MOUNTPOINT        LABEL
loop0          63,3M /snap/core20/1822
loop1         111,9M /snap/lxd/24322
loop2          49,8M /snap/snapd/18357
loop3          49,8M /snap/snapd/18596
loop4          63,3M /snap/core20/1852
sda            59,6G
├─sda1            1M
├─sda2 btrfs      4G /boot
├─sda3 ext4      10G /
├─sda4 swap       4G [SWAP]
├─sda5 ext4      10G /home
├─sda6 ext4       5G /srv
├─sda7 ext4       5G /usr
├─sda8 ext4      10G /var
└─sda9 ext4    11,6G /var/lib
frank@lankeeper:/$

Perhaps someone is looking over that table and can help
me to find the right amount of diskspace for each partition.

With upgrading the Ubuntu system it will use;

• 95 MB for system updates
• 600 MB for programs such gps, bluetooth, WiFi that`s it.
