Cannot update from OSMC menu, ok via apt

When trying to update with the OSMC menu in Kodi, either using manual control, or when the update is crown triggered. The updates of the repositories are downloaded, but it’s end up with a message on the lower part of the screen Insufficient space for update to proceed free somme storage space and try again later . Upgrades with apt under a command line shell work flawlessly.
I have plenty of space on my system as show:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        172M     0  172M   0% /dev
tmpfs           177M  4.8M  172M   3% /run

tmpfs           177M     0  177M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           177M     0  177M   0% /sys/fs/cgroup
/dev/mmcblk0p1  240M   24M  217M  10% /media/DEE7-AFB2
tmpfs            36M     0   36M   0% /run/user/1000

There is no record of this insufficient space in the log nor when I look at messages with journalctl.

How about your /boot partition?
sudo mount /boot
df -h

Ok I just have seen the messages in the log, a spurious character in my fstab was breaking the mount of the /boot partition.
This is now ok. Sorry for this post. I got too focused on this insufficient space message.
