Bug#586434: Let's clean the apt cache
On Saturday 19 June 2010, Martin Michlmayr wrote: I see no reason for leaving .deb files in /var/cache/apt/archives on a fresh installation, so let's run apt-get clean before reboot. This has been suggested and discussed before. IIRC (but I may be mistaken) Joey has always been against it. The main reason IIRC is that leaving the packages makes it unnecessary to download them again if part of e.g. tasksel fails for whatever reason and the user has to install some packages manually (after ignoring that error - which is a real option as the base system should still be functional - and completing the installation). Think of a (partially) failed desktop install over a relatively slow network connection. IMO that argument is valid, but I also don't think that by itself it's enough to decide one way or another. I have no very strong feelings about this. Cleaning up is a good idea in general, but I don't think there is any huge gain in doing it here. I don't see any real problem with leaving the system admin responsible to do this cleanup (which he has to do anyway for any later package installs/updates). Any disk space savings are IMO illusionary as the cache will fill up again anyway during later updates and any system that does not have sufficient disk space to hold a decent package cache will also have serious problems during later stable updates. I can only see a real gain for installs to embedded systems that are not expected to be updated in any regular way. But those should not be installed using D-I anyway, or at least already always require some customized post-installation. Note also that this is not an issue for packages that are installed from CD as they are not copied to the cache. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.

Note that the above argument is only really valid for packages installed *after* base-installer. If base-installer fails we generally consider the whole installation broken so only cleaning the cache at the end of that (and not also during finish-install) could be something to consider. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.

I mainly mean upgrades from one stable release to the next (e.g. lenny - squeeze). Point releases and individual security updates are much smaller and thus less of a problem. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Quoting Frans Pop (elen...@planet.nl): The main reason IIRC is that leaving the packages makes it unnecessary to download them again if part of e.g. tasksel fails for whatever reason and the user has to install some packages manually (after ignoring that error - which is a real option as the base system should still be functional - and completing the installation). Think of a (partially) failed desktop install over a relatively slow network connection. IMO that argument is valid, but I also don't think that by itself it's enough to decide one way or another. I have no very strong feelings about this. Cleaning up is a good idea in .../... Since yesterday, I was trying to find out why I was recently wondering the same thing...and I finally found today..:-) Indeed, I witnessed my son installing Debian on a Dell mini 9 netbook. He did choose a default desktop install (with Gnome and stuff) as these beasts are powerful enough for such heavy desktop environment. Still, he was monitoring the disk space ans was wondering whether everything would fit in, particularly at the critical moment where .deb files are downloaded...and the time they're all installed. I explained him that it if goes well (it did) he should apt-get clean after the installation so that downloaded files no longer eat the short disk spaces he has. And, of course, he asked me THE question: but why don't you guys clean this out automatically at the end of the install? I have to admit that I was having hard times finding a good argument to explain..:-) So, yes, I'd vote to have, by default a cleaning of the package cache at the end of the install. IMHO, that fits the most common use case. Maybe, for more corner cases where keepign the cache would be good, could we have a low priority option (or a preseed-only choice) to *not* clean the cache? signature.asc Description: Digital signature

I don't think it has anything to do with user choice or preseeding. Making this a debconf option makes absolutely no sense IMO. The only reason I see to keep the cache is when some packages (after base-installer) fail to install. If we want to cover that case it should be detected automatically by testing the result of tasksel [1]. The final cleanup could be omitted in that case. [1] Checking installation of packages using apt-install is much harder to do as there are many different calls and failure may be expected in some cases. It also gains much less as their total size is much less. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

You missed the main point. apt-install can fail without there being an error (example: package being apt-installed isn't available; this is quite common). So you cannot test the result. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

[Martin Michlmayr] I've done it after you get the Installation complete message. Can you confirm that this is late enough? Yes. The last Debian Edu script is at 13debian-edu-profile-udeb before the installation complete message. The LTSP build is done in its own udeb between pkgsel and finish-install. But I would suggest to move it even later, perhaps as late as 60, just after the backup network setup is done.
