[Bug 1766046] Re: dpkg-deb error processing libc6_2.27, libzstd.so.1 is missing

Tue Apr 24 23:48:33 UTC 2018

===As requested ===
$ dpkg -S libzstd.so.1
libzstd1:amd64: /usr/lib/x86_64-linux-gnu/libzstd.so.1.3.3
libzstd1:amd64: /usr/lib/x86_64-linux-gnu/libzstd.so.1

$ ls -l /usr/lib/x86_64-linux-gnu/libzstd.so*
ls: cannot access '/usr/lib/x86_64-linux-gnu/libzstd.so*': No such file or directory

===Plus some more things that might be of interest===

Yet the package claims to be installed
$ dpkg -l |grep libzstd
ii  libzstd1:amd64                             1.3.3+dfsg-2ubuntu1                 amd64        fast lossless compression algorithm

Try to purge it
$ sudo apt-get purge libzstd1

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dictionaries-common : Depends: debconf (>= 1.5.5) but it is not going to be installed or
                                debconf-2.0
                       Depends: libtext-iconv-perl but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Same failure after creating empty libzstd.so files with touch (them removed them).

Nor is the libzstd1 package in the /var/cache/apt/archives directory.

Tried to download the libzstd1 package:
$ sudo apt-get download libzstd1
Get:1 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 libzstd1 amd64 1.3.3+dfsg-2ubuntu1 [189 kB]

Nothing showed up in /var/cache/apt/archives.

Title:
  dpkg-deb error processing libc6_2.27, libzstd.so.1 is missing

Status in glibc package in Ubuntu:
  Incomplete

Bug description:
  Several updates of Ubuntu 18.04 worked, but yesterday, the update
  failed because of some missing file in libc6_2.27-3ubuntu1_amd64.deb
  and libc6_2.27-3ubuntu1_i386.deb

  While updating Ubuntu 18.04, the update failed with a failure to find
  libzstd.so.1 in the libc6_2.27--3ubuntu1_i386 and
  libc6_2.27-3ubuntu1_amd64.deb packages.  Oddly, another problem
  (1027076) was reported on askubuntu for a missing libzstd in package
  htop_2.1.0-3_amd64.deb.  The libzstd should be in its own package,
  according to apt-file search.
