Installation has changed

Hello,

There has been a recent update of the graph-tool installation
instructions for Debian & Ubuntu (i.e. also for Linux Mint):

https://git.skewed.de/count0/graph-tool/-/wikis/installation-instructions#gnulinux

For my Linux Mint 19.2 (Tina) system, I adjusted /etc/apt/sources.list
accordingly:

deb http://downloads.skewed.de/apt bionic main

Unfortunately, apt-get update produces the following error:

   N: Skipping acquire of configured file 'main/binary-i386/Packages' as
   repository 'http://downloads.skewed.de/apt bionic InRelease' doesn't
   support architecture 'i386'

Next, I tried to install graph-tool on another computer which has Linux
Mint 18.3 (Sylvia) on it. For this I would need DISTRIBUTION = xenial.
Unfortunately, it seems that graph-tool does not support xenial anymore
:frowning:

Any help is appreciated...

Best regards
Rolf

I have re-organized the apt repository to simplify and automatize the
package generation, and I have decided to drop the i386 architecture
since I didn't think anyone was using that any longer, and that saves a
lot of time and effort.

But it seems I was wrong... Are you really using a 32 bit i386 CPU in 2020?

Next, I tried to install graph-tool on another computer which has Linux
Mint 18.3 (Sylvia) on it. For this I would need DISTRIBUTION = xenial.

:frowning:

Xenial is super old and does not compile graph-tool due to a lack of
compiler with C++17 support.

Hello Tiago,

I don't believe the hardware requirements have changed from xenial to
bionic.

That was just a guess. I have really no idea why the upgrade didn't
work.

It's out of my hands. That release is frozen in time, and it includes
only GCC 5, where we need version 7 or above.

OK, I see. I will then simply work with the frozen version of graph-tool
which I currently have on that computer.

Thanks again for your help and for providing graph-tool!

Best regards
Rolf

Hello everyone,

I also start to have a problem with graphtool installation.
I use it in google colab and have to install the library everytime.

I use the following code:
!echo "deb http://downloads.skewed.de/apt/bionic bionic universe" >>
/etc/apt/sources.list
!sudo apt-key adv --keyserver keys.openpgp.org --recv-key 612DEFB798507F25
!sudo apt-get update
!sudo apt-get install python3-graph-tool

This code does not work anymore. Error that I've got:
E: The repository 'http://downloads.skewed.de/apt/bionic bionic Release'
does not have a Release file.

I kindly ask you to give me an advice how I can solve this issue.

Best regards

The line should be:

   deb http://downloads.skewed.de/apt bionic main

as is specified in the documentation.
