Port to 20.04

[rakshith-ravi]

I couldn't find a replacement for these packages:

libcloog-isl4
libelektra-dev
libiculx60
libmariadbclient18
libntdb1
libpolkit-backend-1-0
libsane-extras
libsane-extras-common
libv8-3.14.5
libv8-dev
vdpau-va-driver

Any idea on what to do about these packages? The docker image builds successfully without them though.

Locally, running 20.04, I see libmariadbclient-dev -- can you check that again? I can confirm that cursory searches do not yield results for the others.

[rakshith-ravi]

Oh yeah, I forgot to mention that. The libmariadbclient-dev package exists, but seems to be clashing with libmysqlclient-dev. It wouldn't let me install them together.

[rakshith-ravi]

Okay hold on, I think I may have confused the packages. libmariadbclient-dev works, but libmariadbclient18 doesn't seem to have an installation candidate. In fact, my PR has the libmariadbclient-dev and libmariadbclient-dev-compat package in it.

Sorry about the confusion. I'll update the initial post

libmariadbclient18

This is left over from the initial commit, so I think as long as we have the development headers it's fine not to keep it.

libcloog-isl4
libntdb1

As mentioned in #42 (comment) I think it's fine to get rid of these.

libelektra-dev

This has not be packaged upstream, see ElektraInitiative/libelektra#3412. I think it's fine not to keep it in the meantime, we can add it back later if/when it gets packaged.

libiculx60
libpolkit-backend-1-0
libv8-3.14.5
libv8dev
vdpau-va-driver

These are also from the initial commit, I'm ok with not keeping them. There doesn't seem to be a replacement package in 20.04.

libsane-extras
libsane-extras-common

These appear to have been renamed to libsane and libsane-common, try adding those.

[rakshith-ravi]

Done. libsane and libsane-common is added. Not sure why the travis build was failing though. Something about a task not found.

[jyn514]

The error is

Lint error: packages.txt is not sorted

You can fix it with sort packages.txt > tmp && mv tmp packages.txt.

[jyn514]

Asked to remove a few duplicate versions. I haven't checked whether they were explicitly requested, if any of them were then don't remove them. You can check with git log -p packages.txt | grep <package name>.
Also, I want to check at some point that all the removed packages are no longer present in 20.04, I don't have time right now.

Updated

Thanks so much for working on this!
