Solbuild update no longer works for me, where am I wrong?

~ $ sudo solbuild update
✓  Using default profile name=unstable-x86_64
chroot: impossibile eseguire il comando "/bin/sh": File o directory non esistente
Translation help:
impossibile eseguire il comando = unable to execute command
File o directory non esistente= File or directory does not exist

alfisya It's been a while since the last update, however the reset worked, thanks!
