APT error during installer

[Loïc Minier]

Hi

I get an APT error in a popup during install (see screenshot).

I can still install though

Bye

i thought that was a universal karmic problem

[Marchombre (princestark)]

Is there any harm in there ?

Marking this low. It blocks progress until you ok it, but it doesn't seem to prevent the install from succeeding.

[Loïc Minier (lool)]

Patrice, what lets you think it's a bug in ubiquity?

[Patrice Vetsel (vetsel-patrice)]

@Loïc : nothing specifically. I get this bug during desktop amd64 installation process (using ubiquity). So it's not only an "ubuntu-moblin-remix" bug, but may be a problem with ubiquity.

[Loïc Minier (lool)]

Interesting, thanks

This may not block installation, but still needs to be fixed for 9.10

[Phil Norbeck (ptn107)]

I can't reproduce this with the beta image (ubuntu-9.10-beta-desktop-amd64.iso) or the latest daily 10-13-2009 (karmic-desktop-amd64.iso). Tried with both my test machines and a vm.

[Tobin Davis (gruemaster)]

I am able to reproduce this with today's (20091015) karmic-moblin-remix-i386.iso image.

[Paul Larson (pwlars)]

setting importance to high, because this really does need to be addressed before release and still exists in daily builds. It doesn't seem to prevent the install from finishing, but can give the impression that the install is failing

[Omer Akram (om26er)]

have any1 tested the live cd from a cd/dvd rom because the error comes when scanning for cd-rom

[Evan (ev)]

This is triggered by the Moblin CD not having any packages in pool/. APT checks for Packages and Sources files to indicate a valid Debian CD, neither of which are present on the Moblin CD.

[Michael Vogt (mvo)]

Could we simply make ubiquity or apt-setup ignore this error condition? It seems to me like making apt-cdrom accept CDs without Packages should issue a error, but the installer should just ignore it in this case.

[Loïc Minier (lool)]

I checked the debian-cd code, it seems we added code to strip empty Packages files from live CDs in r829; I'm clarifying with Colin whether it's ok to keep them or at least keep one such file.

@Michael: is there a way to distinguish this error condition from others? e.g. we want to fail on I/O errors, but I don't think we want to add logic to check for Packages file before calling APT as it would kind of duplicate the logic.

[Loïc Minier (lool)]

I've included a workaround in debian-cd to keep the Packages file for this project.

[Omer Akram (om26er)]

fixed in 20091019.1?? 20091020 is not out at cdimage

[Loïc Minier (lool)]

Dailies are disabled until release, but slangasek planned a rebuild of moblin remix for today already.

[Loïc Minier (lool)]

I didn't see this bug in RC candidates testing.

[Paul Larson (pwlars)]

Marking the rest of the tasks invalid, this is fixed and working fine in the daily images now

[Loïc Minier (lool)]

I reopened the tasks -- I merely added a workaround in the moblin images which is quite crude.

Probably one of apt-setup or ubiquity should be fixed to ignore CDs with no Packages files, not sure which. I changed the debian-cd scripts to not strip empty Packages files from the CD for the moblin-remix project.

[Loïc Minier (lool)]

(I did lower priority and dropped the milestone though)

[Krisi (krisi1992)]

I'm installing Ubuntu 9.10 from USB, and I got this error.

[Tobin Davis (gruemaster)]

Is this still valid for either apt-setup or ubiquity? Closing as incomplete otherwise.

[Paul White (paulw2u)]

This issue has sat with a status of 'Incomplete' for more than 10 years now without any response so the relevant tasks are being closed as 'Invalid'.

Please feel free to re-open this bug report if this is still an issue when using a currently supported release of Ubuntu and tell us in which release you still experience this issue.
