I get it after updating in Synaptic Manager

I recently did a clean install of Ubuntu 17.04 from 16.10.

error message:-

W: Download is performed unsandboxed as root as file '/var/cache/apt/archives/partial/samba-libs_2%3a4.5.8+dfsg-0ubuntu0.17.04.1_i386.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

    Your running a process that needs root privileges as non-root... – George Udosen Apr 25 '17 at 15:16
  • It is known bug 1522675, after long discussion with developers it is fixed. Please wait some hours or one-two days. – N0rbert Mar 5 '18 at 7:01

Usually apt uses the user _apt to download packages. In your case _apt doesn't have write permission to either /var/cache/apt/archives/partial/ or an existing file /var/cache/apt/archives/partial/samba-libs_2%3a4.5.8+dfsg-0ubuntu0.17.04.1_i386.deb so it downloaded the file as root.

Make sure /var/cache/apt/archives/partial/ and everything below it are writeable for _apt, e.g. by running

sudo chown -Rv _apt:root /var/cache/apt/archives/partial/
sudo chmod -Rv 700 /var/cache/apt/archives/partial/

    I have this problem while using a mounted folder autside of my vagrant VM, so the mounted folder is always belonging to the user vagrant which cannot be changed. How can I solve this there? maybe just disable the warning, because in my Test VM it is not a problem if apt is run by root – rubo77 Jun 21 '18 at 17:22
  • @rubo77 - This fixed that situation for me: github.com/fgrehm/vagrant-cachier/issues/… - setting an explicit owner in synced_folder_opts – Henk Aug 29 '18 at 14:13
  • It also helped me to run this command after chowning and chmoding: sudo chmod -Rv 755 /root/.synaptic/tmp. Afterward, no more error! – Ev- Nov 24 '18 at 7:54
