sudo gainroot works alright...i get the following output:

Busybox v1.10.2 (Debian 3:1.10.2.legal-losso30+0m5) built-in shell (ash)
Enter 'help' for a list of built in commands.

okay...for dkpg --clear-avail there is no output...anyway i typed apt-get update after that and i got the following output...

"E: dpkg was interrupted, you must manually run dpkg --configure -a to correct the problem"

for dpkg --configure -a i get the following output:

"dpkg: parse error, in file '/var/lib/dpkg/updates/0003' near line 1: newline in field name '#padding'
