I'm not certain whether I have bionic-updates enabled, although I have realised the issue has been caused by the versions of packages (namely 1.15.10-2ubuntu0.1) being more recent than 1.15.10-2, I guess this means that the system on which I am installing has indeed had some updates to the original Bionic package list. Apologies for the bug if this means it was filed in error, as this is my first time using Ubuntu in a while I did not expect these two versions to be different.
I have manually downgraded all of the dependencies e.g.: $sudo apt install libcairo-gobject2=1.15.10-2 Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be DOWNGRADED: libcairo-gobject2 0 to upgrade, 0 to newly install, 1 to downgrade, 0 to remove and 0 not to upgrade. Need to get 17.2 kB of archives. After this operation, 0 B of additional disk space will be used. Do you want to continue? [Y/n] y Get:1 http://gb.archive.ubuntu.com/ubuntu bionic/main amd64 libcairo-gobject2 amd64 1.15.10-2 [17.2 kB] Fetched 17.2 kB in 0s (506 kB/s) Which has allowed me to correctly install libcairo2-dev as required. One perhaps useful update to come from this would be adjusting libcairo2-dev's dependencies to include those packages from the Bionic updates. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cairo in Ubuntu. https://bugs.launchpad.net/bugs/1859030 Title: libcairo2 does not install on Bionic (18.04) Status in cairo package in Ubuntu: Incomplete Bug description: Attempt at installing libcairo2-dev on a clean Bionic install fails as follows: $ sudo apt install libcairo2-dev Reading package lists...
