When apt report sizes (needed/available) it uses 'human writing' (e.g. uses MB when it's hundreds megabytes, or GB when it's hundreds gigabytes). But it uses them separately for each number, which leads to misleading (hard to read) output: Space needed: 155 MB / 154 GB available It need some attention to notice that it's 155Mb needed out of 154000Mb available. May be it's possible to use the largest size unit (e.g. GB) to display this message in the one scale: Space needed: 0.2 GB / 154 GB available Space needed: 155 MB / 154123 MB available
