couldn't be accessed by user _apt

[Ashkan Taslimi]

How can I fix this the following problem:

W: Can't drop privileges for downloading as file
'/tmp/adt-run.ZlyfuQ/deps/afl_2.10b-1_amd64.deb' couldn't be accessed by
user '_apt'. - pkgAcquire::Run (13: Permission denied)


Thanks in advance,
Ashkan

PS:
adt-run --apt-source afl --output-dir=/home/user/Documents/tmp/$start_date
--- adt-virt-ssh  -H localhost -lroot -Proot -p10022

PSS: I can ssh to the VM
