[SOLVED] Update fails: Update cannot proceed without at least 500M space

[dersucher]

Hello together,

I use the great audioplayer since many years. At this place: Many thanks to all contributors for the great work!

a few days ago, I tried to update my installation with this error message "Update cannot proceed without at least 500M space". The last Update I got the same error und reinstaled all new. But this time I took a deeper look.

There is still enough free space.

Code:

Filesystem      Size  Used Avail Use% Mounted on
udev            886M     0  886M   0% /dev
tmpfs           185M  2.4M  183M   2% /run
/dev/mmcblk0p2   29G  3.9G   24G  15% /
tmpfs           925M     0  925M   0% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
/dev/mmcblk0p1  253M   41M  212M  17% /boot
/dev/md0        3.7T  1.1T  2.6T  30% /media/raspberry
tmpfs           185M     0  185M   0% /run/user/1000

So I read a litte bit in the php code. In file /var/www/sys-config.php at line 73

Code:

$space = sysCmd("df | grep /dev/root | awk '{print $4}'");

but it seems that there is no /dev/root so the free space retrival is 0.

I commented some lines out below and the update worked very fine.


It would be great, if you take a look and do a modificaton in the code.


Many thanks in advance,
Friedemann

P.S.:

Code:

ln -s /dev/mmcblk0p2 /dev/root

could be the solution for my installation?
