Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find. ** Information type changed from Private Security to Public -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libpng in Ubuntu. https://bugs.launchpad.net/bugs/1854498 Title: package libpng12-0 1.2.54-1ubuntu1 failed to install/upgrade: trying to overwrite shared '/usr/share/doc/libpng12-0/changelog.Debian.gz', which is different from other instances of package libpng12-0:amd64 Status in libpng package in Ubuntu: New Bug description: /var/cache/apt/archives/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) ProblemType: Package DistroRelease: Ubuntu 16.04 Package: libpng12-0 1.2.54-1ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-70.79~16.04.1-generic 4.15.18 Uname: Linux 4.15.0-70-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.21 AptOrdering: libpng12-0: Install libpng12-0: Configure libpng12-0: Configure NULL: ConfigurePending Architecture: amd64 Date: Fri Nov 29 08:19:09 2019 Dependencies: gcc-6-base 6.0.1-0ubuntu1 libc6 2.23-0ubuntu11 libgcc1 1:6.0.1-0ubuntu1 zlib1g 1:1.2.8.dfsg-2ubuntu4.1 DpkgTerminalLog: Preparing to unpack .../libpng12-0_1.2.54-1ubuntu1.1_amd64.deb ...
