<p>Quite regularly, I let my Debian Sid/Unstable chroot stay untouch
for a while, and when I need to update it there is not enough free
without changing the APT mark for the package (ie the one recording of
the package was manually requested or pulled in as a dependency). To
use it, simply run it as root from the command line. If it fail, try
-'apt install -f' to clean up the mess and run the script again.</p>

upgrade. The option to ignore a package is there to be able to skip
the packages that are simply too large to unpack. Today this was
'ghc', but I have run into other large packages causing similar
problems earlier (like TeX).</p>
+<p>Update 2018-07-08: Thanks to Paul Wise, I am aware of two
+alternative ways to handle this. The "unattended-upgrades
+--minimal-upgrade-steps" option will try to calculate upgrade sets for
+each package to upgrade, and then upgrade them in order, smallest set
+first. It might be a better option than my above mentioned script.
+Also, "aptutude upgrade" can upgrade single packages, thus avoiding
+the need for using "dpkg -i" in the script above.</p>
