I have a PC that usually used for Yocto image building. Now I need to add ROS2 packages to the same image. After all it's turned out the disk is full so I've connected a SSD external disk to build the image on it. I did the same steps as before, run the same command etc. but after the build starts if crashed at the first package. I've reinstalled all the sources from zero, I've deleted tmp and ssstate-cache but nothing help. I don't understand what this error says.
As I see Yocto fail to write something into ssstate-cache/61, I don't really know what that is. A user has read/write permissions.
The build system: Ubuntu 20.04
Yocto version: zeus
In the linked error log, the relevant part is:
SignatureGeneratorOEBasicHash.dump_sigtask(fn='/media/sw/Samsung/yocto/sources/poky/meta/recipes-extended/texinfo-dummy-native/texinfo-dummy-native.bb', task='do_fetch', stampbase='/media/sw/Samsung/yocto/build-xwayland/sstate-cache/61/sstate:texinfo-dummy-native::1.0:r0::3:610ed4b8e8bf78bbcd4a667b6645a0276f5c8bfce5de4822923850d44d032bbe_fetch.tgz.siginfo', runtime='customfile:/media/sw/Samsung/yocto/build-xwayland/tmp/stamps/x86_64-linux/texinfo-dummy-native/1.0-r0'):

except (OSError, IOError) as err:

It is likely that the new name is not valid for the target disk filesystem. Typically the : character is invalid on FAT/NTFS filesystems. Native Linux filesystems like Ext4, XFS and Btrfs will not have this limitation.
