<![CDATA[Installing Focal on FP2]]>Hello!

I noticed that a Focal 20.04 devel channel is available for Fairphone2 🙂
It was announced in Q&A 139 and discussed again in Q&A 145

Note that the installer shows also a "utnext" channel but this one is empty.

I tried today the installation with the UBPorts installer and although the installer says OK, the update fails on device...

Here is the last lines of /lcache/recovery/last_log:

Someone responded "oh crap i forgot to fix that". I did not follow up as it was not that important to me.

Here is the file size:

  • 16.04 Stable (version 23)

    • ubports 356 Mo compr., 1379 Mo extr.
    • device 69 Mo compr., 181 Mo extr.

  • 20.04 Devel (version 146)

    • rootfs 456 Mo compr., 1664 Mo extr.
    • device 88 Mo compr., 227 Mo extr.

When 16.04 is installed, the extracted size ( 1379+181 = 1560 Mo) corresponds to this partition:

df -h
Filesystem                      Size  Used Avail Use% Mounted on
/dev/loop0                      2.0G  1.6G  241M  88% /

What I don't understand is why 20.04 installation is failing; while the extracted size (1664+227 = 1891 Mo) should still be inferior to the 2 Go partition size... 🤔

EDIT: I made a trial on my computer. Decompressing both rootfs and device tar.xz on an empty ext4 image file, the used space is 2,041,232 Kb; so more than the phone partition size!
There is not enough free space on the partition to hold the data. The deficit is about 170 MB.
