The calculation apt does is based on the Installed-Size comparing what the old versions used vs. what the new versions use. The size increase after the installation is complete might be (at least) 8 MB in this case. This does not include auto-generated files, those downloaded while configuring (non-free packages), … as those files are not included in the package and are hence not part of the value of Installed-Size (that is generated by dpkg at package build time). The problem here is, I think, something else through: texlive-fonts-extra has an Installed-Size of 1.892 MB. If dpkg installs the upgrade by placing the .dpkg-new files alongside the old files before replacing them all the installation process might need 2 GB of free space temporarily which you don't have. (I don't know the inner workings of dpkg enough to know how it behaves, but I suspect it does so for handling reverts/aborts) Maybe we can look for the biggest (upgraded) deb to install and warn if the system hasn't enough free space to unpack it entirely. This would be off in edge cases of multi-partitioned systems, but those folks have problems with the 'Space needed' info anyhow as we don't know where the data will end up (/boot, /usr, /opt, …). While at it, we might want to check that the upgrades fit before any reductions apply (be it upgrades or removals) as we don't really know in which order they will apply (well, we kinda do, but that might be overkill to calculate). Especially the removals are done last, which if we take texlive-fonts-extra as an example makes a big difference on this example system. Best regards David Kalnischkies
