How can ubuntu make such mistakes? I hope a patch comes immediately, because for a new release is very shameful!

This apparently fixes a Lintian warning. Also the soname change might be justified by the new version breaking most 3rd party plug-ins even if the library version number doesn't any bigger change than any ordinary new version of the library: libsane 1.0.25 in zesty includes libsane.so.1.25 libsane1 1.0.27 in artful includes libsane.so.1.27 The breaking of all plug-ins might be an upstream bug - which is allowed in an experimental package, but is unfortunate as in Ubuntu this package went mainstream; The library rename is an additional factor that makes it impossible to install any scanner drivers for libsane that are distributed as a .deb unless the driver distributors recompiles against Ubuntu 17.10+. It is to note that depending on the manufacturer for many old scanners there won't be new versions of the plug-ins that are recompiled like this; Adding a Provides: libsane to the library might therefore make some plug-ins work, perhaps. Test Case ========= Visit http://support.epson.net/linux/en/iscan_c.html Download the amd64 deb .tar.gz Unzip it. Install the iscan .deb from the core folder. It won't install before this SRU because it Depends: libsane Regression Potential ==================== The fix here was proposed to the Debian maintainer in July but there's been virtually zero response on it. In the meantime the workaround that was proposed initially has started to result in automatically uninstalling gtk - which makes the system basically useless. It doesn't seem like adding the Provides will make things any worse for third-party drivers but it has a goodme chance of making things better for some. Impossibility of workarounds ============================ Just installing an old version of libsane is impossible as it uninstalls libgtk (which depends on libsane1 which conflicts with libsane) making the system basically useless. Original Bug Report =================== I don't know if that can be prevented in the long run. But both brscan (for my brother scanner) and iscan (for my epson scanners) have been broken by the change from libsane to libsane1. For iscan I have unpackaged the debian package, changed the dependency it contains from libsane to libsane1 and installed the changed package. But even then my epson scanners no more work leaving me without any scanner => Reporting a bug.
