What to do in the situation of "installed some dependencies to build a package and the build still failed, now left with dependencies I didn't need"?

What to do in the situation of "installed some dependencies to build a package and the build still failed, now left with dependencies I didn't need"?

This seems as if it could eventually cause bloat to the system.

I thought:

  • always try installations/builds to a "sandbox" OS first, like virtual box Ubuntu or something

  • organize main OS so that it's possible to do full clean installs of OS from time to time to clear all the junk

Anything else?

If you do a `sudo apt --simulate build-dep <packagename>` it will show you all the dependencies that got installed or should have been installed, so you can reverse it and use `sudo apt remove <listofdependencies>`.

@mavavilj It wouldn't hurt to try.

@mavavilj Depending on the app, you can also check with whoever the developer is and see if they have that list of dependencies for that specific app.

All dependencies pulled in by apt-get e.g. using the build-dep command are marked as "automatically installed". Once the package that needed them is removed, they can be removed by an "apt-get autoremove" command.

All dependencies you installed explicitly yourself are marked as "manually installed". You need to explicitly remove them again to get rid of them. So indeed, you will need to take note of the packages you installed so you can clean up if your compilation effort ends up failing.

Something that may help you after the fact to identify packages installed on the date that you did the compilation. You can do so in the output of grep install /var/log/dpkg.log (source and further info).

What if one installs using apt-get and dependencies succeed, but complete installation fails? Do they become available to autoremove?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
