Installation problem: Unmet dependencies error in Colab

graph-tool
1

Hi Tiago,

Since a couple days ago, I get unmet dependencies error when trying to install graph-tool on Colab. I use the Colab notebook instructions in the document with no change.

!cat /etc/*release

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=22.04
DISTRIB_CODENAME=jammy
DISTRIB_DESCRIPTION="Ubuntu 22.04.2 LTS

!echo "deb http://downloads.skewed.de/apt focal main" >> /etc/apt/sources.list
!apt-key adv --keyserver keyserver.ubuntu.com --recv-key 612DEFB798507F25
!apt-get update
!apt-get install python3-graph-tool python3-matplotlib python3-cairo

Error: The following packages have unmet dependencies:
 python3-graph-tool : Depends: libboost-context1.71.0 but it is not installable

Thank you,

It seems colab replaced focal with jammy. Just replace focal with jammy in the installation steps.
