** Description changed:
Recently we got new versions for synaptic 0.82+build1 & apt 1.1.3, but
now get that error when installing/upgrading some packages:
Setting up libc6-dbg:amd64 (2.21-0ubuntu5) ...
Processing triggers for libc-bin (2.21-0ubuntu5) ...
W: Can't drop privileges for downloading as file '/root/.synaptic/tmp//tmp_cl' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
From nautilus, i'm seeing a /root/ folder locked (x on its icon) and the
folder is empty (no /.synaptic/ sub-folder or file), so the above error.
- =======================================================================
- The real problem is : there is no _apt user on the system (see #808802 MV comments)
+ oem at u64:~$ ls -l .synaptic
+ total 4
+ -rw-rw-r-- 1 oem oem 0 Aug 25 11:19 options
+ -rw-rw-r-- 1 oem oem 236 Aug 25 11:19 synaptic.conf
- grep -B2 _apt /var/lib/dpkg/info/apt.postinst
+ oem at u64:~$ ls -l /var/lib/apt/lists/
+ ....
+ -rw-r----- 1 root root 0 Sep 20 06:36 lock
+ drwx------ 2 _apt root 16384 Sep 24 15:25 partial
+ ......
- # add unprivileged user for the apt methods
- adduser --force-badname --system --home /nonexistent \
- --no-create-home --quiet _apt || true
-
- # Fixup any mistake in the home directory of the _apt user
- if dpkg --compare-versions "$2" lt-nl 1.1~exp10~; then
- usermod --home /nonexistent _apt
- ======================================================================
- and also a workaround:
- sudo chown _apt /var/lib/update-notifier/package-data-downloads/partial/
+ oem at u64:~$ sudo ls -l /var/lib/update-notifier/package-data-downloads/
+ .....
