Help with issues regarding installation of Debian

Which distro

Postby jpaulb » 2020-05-04 21:06

I have been away from Debian for quite a while and was thinking of installing it on my video editing box. That is if I can get Lightworks 2020.1 to install. I tried to install lightworks on testing which failed with the warnings.
dpkg: dependency problems prevent configuration of lightworks:
lightworks depends on libpango1.0-0 (>= 1.18.0); however:
Package libpango1.0-0 is not installed.
lightworks depends on nvidia-cg-toolkit; however:
Package nvidia-cg-toolkit is not installed.

I read in the lightworks forum that I would have to install Debian unstable to get it to work.. I have been searching debian.org for over an hour without finding a link to down load Sid.
Please help.

I wouldn't know unless I tried to install it myself. but a sid mini.iso can be downloaded from this link
libpango1.0-0 is in the Debian main repository but nvidia-cg-toolkit is available from the non-free repository which it seems you have not added to the /etc/apt/sources.list
Querying the Debian archive database shows that the package versions for nvidia-cg-toolkit are the same in both testing and sid so "upgrading" to sid won't make any difference with regard to that package. libpango1.0-0 is not currently available in testing and the version in sid is a debports only for powerpcspe and arm64. Therefore it might be a better idea to try and install it in current stable and backport any packages if necessary.
Code: Select all
libpango1.0-0     | 1.42.4-7~deb10u1 | stable                  | amd64, i386
libpango1.0-0     | 1.42.4-8~deb10u1 | buildd-proposed-updates | amd64, i386
libpango1.0-0     | 1.42.4-8~deb10u1 | proposed-updates        | amd64 i386
nvidia-cg-toolkit | 3.1.0013-5       | stable/non-free         | source, amd64, i386
nvidia-cg-toolkit | 3.1.0013-5       | testing/non-free        | source, amd64, i386
nvidia-cg-toolkit | 3.1.0013-5       | unstable/non-free       | source, amd64, i386

If you want to use it for productive work, Sid is a poor choice.
It will take up a lot of admin time and may contain potentially catastrophic bugs, as well as having the potential to break at any time.

I've had another look at this and tried installing the lightworks deb in current stable but it doesn't look at all promising:
Code: Select all
# dpkg -i lightworks-14.5.0-amd64.deb
Selecting previously unselected package lightworks.
(Reading database ... 363866 files and directories currently installed.)
Preparing to unpack lightworks-14.5.0-amd64.deb ...
Unpacking lightworks (14.5.0.0) ...
dpkg: dependency problems prevent configuration of lightworks:
 lightworks depends on libc++1 (>= 1.0); however:
  Package libc++1 is not installed.
 lightworks depends on libjpeg8 (>= 8c); however:
  Package libjpeg8 is not installed.
 lightworks depends on nvidia-cg-toolkit; however:
  Package nvidia-cg-toolkit is not installed.

dpkg: error processing package lightworks (--install):
 dependency problems - leaving unconfigured
Processing triggers for bamfdaemon (0.5.4-1) ...

Processing triggers for desktop-file-utils (0.23-4) ...
Processing triggers for mime-support (3.62) ...

Errors were encountered while processing:
 lightworks

And even worse:
Code: Select all
# apt install nvidia-cg-toolkit

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 lightworks : Depends: libc++1 (>= 1.0) but it is not going to be installed
              Depends: libjpeg8 (>= 8c) but it is not installable
 nvidia-cg-toolkit : Depends: libcg (= 3.1.0013-5) but it is not going to be installed
                     Depends: libcggl (= 3.1.0013-5) but it is not going to be installed
                     Depends: nvidia-cg-dev (= 3.1.0013-5) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
# apt --fix-broken install
Reading package lists... Done

The following packages will be REMOVED:

Those are old dependencies. How old was that forum post that said you needed Sid---2011?

Good news!
I have solved how to install lightworks in Debian 10 stable, which is obviously preferable to using testing or sid as noted above by dilberts_left_nut.
You will, by the way, need to enable the non-free repository first in /etc/apt/sources.list
The secret is to use aptitude rather than apt to resolve the dependencies:
Code: Select all
root@kedaha:~# aptitude install libc++1  libcg libcggl nvidia-cg-dev nvidia-cg-toolkit

You also need libjpeg8 (>= 8c), which was not installable because it is not in the repositories.
However, it can be downloaded from snapshot.debian.org. I downloaded this libjpeg8_8d1-2_amd64.deb and installed it from my Downloads folder:
Code: Select all
# dpkg -i libjpeg8_8d1-2_amd64.deb
# dpkg -i lightworks-14.5.0-amd64.deb
