[15:59] Is there a way to prevent ubiquity from installing certain packages? For reference, I'm still using (and customizing) the ubuntu-18.04.4-desktop-amd64.iso [16:00] e.g., I'd like to avoid installing the `transmission*` packages, if I could. [16:12] realtime-neil: my guess: https://www.debian.org/doc/manuals/debian-reference/ch02.en.html#_tweaking_candidate_version "never install the package even if recommended " [16:13] I am guessing transmission is a dependency of ubuntu-desktop, no clue what will happen when that install fails, last guess: the installer stops [16:27] ubuntu-desktop Recommends transmission-gtk, it doesn't depend on it. [16:28] But ubiquity works by copying a squashfs, so you can't avoid installing the packages there as such, only arrange to remove them afterwards. [17:59] cjwatson: understood and I concur, but I have demonstrated with my own tests that the unmodified ubuntu-18.04.4-desktop-amd64.iso ubiquity installs the `ubuntu-desktop` virtual package. [18:00] CarlFK: that's a good idea --- I'll try that next [18:01] Indeed - I don't think that contradicts me [18:06] cjwatson: yep, i misread that; your implication being that, despite what happens with the squashfs, there's this implicit `apt-get -y install ubuntu-desktop` happening _after_ the unsquashfs that I can't control. [18:07] Well, I can't control it _yet_, at any rate. [18:09] realtime-neil: That wasn't my implication; I was just saying that transmission-gtk is in the squashfs so it isn't ordinarily possible to stop ubiquity installing it. (But I missed that you're editing squashfses, so this probably isn't so relevant. Carry on.) [18:10] If you're editing the squashfs then you'd just arrange for the squashfs not to have that package installed. [18:25] Wow, okay, apparently it _is_ already installed within the filesystem.squashfs ... I missed that yesterday
