tickvue and Ubuntu 16.04

[Ralf Mardorf]

Hi,

http://packages.ubuntu.com/ doesn't find tickvue by official
repositories.

Run

dpkg -I /var/cache/apt/archives/package_name.deb

to get a list of the libraries that are required. However, the
information ">=" not necessarily means that each lib ">" necessarily
will work. Chances are good that if it requires e.g. libfoo (>= 1.0)
and Ubuntu 16.04 should provide libfoo (>= 1.5), that it will still
work, but it unlikely would be still usable, assuming the so
called "soname" changed, IOW not the dot release, but the major release,
so if Ubuntu 16.04 should provide libfoo (>= 2.0), it unlikly would run.

You could backup such a lib

libfoo.so -> libfoo.so.1.0.0
libfoo.so.1 -> libfoo.so.1.0.0
libfoo.so.1.0.0

Don't backup and restore "libfoo.so", this is only needed to build and
should be used from the new package. But backup and restore libfoo.so.1
and libfoo.so.1.0.0. You need to run

  sudo ldconfig

after restoring the lib and link.

You could see, if this should be required by taking a look at the
version of the libs at http://packages.ubuntu.com/ .

If you don't have the package available in /var/cache/apt/archives/ or
any other pass, the info provided by

apt-cache showpkg pluma | grep -A1 Dependencies:

does the job, too. The missing ">=" are not that important. Again,
usually different dot release don't break a package, but if the major
release changed you unlikely could contiue using the package, resp. you
need to copy the old libraries.

There's still a handicap for the package management, since the package
providing tickvue does confuse the package management, assuming that
Ubuntu 16.04 shouldn't provide the required dependencies.

Copy the files of the package, listed by

dpkg -L

then remove the package and restore the files on Ubuntu 16.04, don't
try to reinstall the package.

Regards,
Ralf
