Help with issues regarding installation of Debian

[SOLVED]Stretch upgrade 9.0.0 to 9.1.0 fails from update DVD

Postby gurfle » 2017-08-01 16:56

I used the first three 9.0.0 DVDs for an original installation successfully, but now there is a problem with those three as well as the new 9.1.0 update DVD:

"apt-cdrom add" on the necssary DVDs puts the following in /etc/apt/sources.list
Code: Select all
deb cdrom:[Debian GNU/Linux 9.1.0 Update DVD 20170722: i386 DVD 1]/ stretch contrib main non-free
deb cdrom:[Debian GNU/Linux 9.0.0 _Stretch_ - Official i386 DVD Binary-3 20170617-14:24]/ stretch contrib main
deb cdrom:[Debian GNU/Linux 9.0.0 _Stretch_ - Official i386 DVD Binary-2 20170617-14:24]/ stretch contrib main
deb cdrom:[Debian GNU/Linux 9.0.0 _Stretch_ - Official i386 DVD Binary-1 20170617-14:24]/ stretch main

"apt-get update" gives some warnings, but appears to otherwise work:
Code: Select all

Why are the Release files not found? They were recognized on the exact same DVDs during the original 9.0.0 installation.
EDIT: Actually not; I forgot the warnings just got suppressed during successful 9.0.0 package installation because I had used the "trusted=yes" option for those sources in sources.list.

"apt-get upgrade" however fails completely:
Code: Select all

Re: Stretch upgrade 9.0.0 to 9.1.0 fails from DVD

Perhaps you should declare them "trusted" in your 'sources.list' file? In other words:
Code: Select all
deb [trusted=yes] cdrom:......

Re: Stretch upgrade 9.0.0 to 9.1.0 fails from DVD

Postby gurfle » 2017-08-01 18:43

Thanks for the suggestion, luvr. It has helped me narrow down where the source of the problem might be, but doesn't quite solve it yet:

While the update warnings go away with "trusted=yes", the upgrade still fails the same way.

However I now understand why I saw no issues in the original 9.0.0 installation:

"trusted=yes" had been set at that time, and apparently package install from the 9.0.0 DVDs didn't (and still doesn't) care about the "unfound" Release files.

So this sounds like the 9.1.0 update DVD requires some additional security measure to actually install packages that the old 9.0.0 DVDs don't, even though they all generate the same warning in "apt-get update" without "trusted=yes". In other words there is something different about the new 9.1.0 update DVD itself compared to the original set for 9.0.0. The latter are no longer available for download in the standard debian repository, but it would be interesting to know whether the regular (i.e. not the "update") 9.1.0 DVDs behave like the old 9.0.0 DVDs or the new update 9.1.0 DVD.

Any suggestions on how get rid the update warning? That way I could at least see if whatever problem causes the update warning is or is not related to the package installation failure from the 9.1.0 DVD.

P.S.: The problem persists with:

1) An amd64 update DVD on another, otherwise identical stretch installation (original problem posted here was for an i386 machine).
2) All DVD images mounted as iso files (with correct ACL settings as discussed here).

So the architecture of the DVD has no bearing on the problem (which one wouldn't expect) and it seems unrelated to a file system mount point or permission issue.

The only other option I can think of is “allow-insecure=yes”, but I’m unsure if that’s a stronger or a weaker option than “trusted=yes”. Maybe try setting both of them, like so:
Code: Select all
deb [ trusted=yes allow-insecure=yes ] cdrom:......

The original 9.0.0 DVDs can still be downloaded from the Index of /cdimage/archive/9.0.0 pages. I’m pretty sure there exists a path to get there from the Debian Home Page, but I keep getting lost trying to find my way to it.

Not quite sure if this applies to your case, but if you’re using a repository that “used to be secure, but can no longer be verified,” then you may want to try the “allow-downgrade-to-insecure=yes” option as well:
Code: Select all
deb [ trusted=yes allow-insecure=yes allow-downgrade-to-insecure=yes ] cdrom:......

Thanks for the URL to the original 9.0.0 images. I was mainly interested if anyone had relevant experience with the 9.1.0 images, as I am not desperate enough yet to start all over downloading those.

Unfortunately these don't help either, nor does adding "allow-weak=yes" which I thought to try because of the "weak" message in the errors, e.g.
Code: Select all
Err:0 cdrom://[Debian GNU/Linux 9.1.0 Update DVD 20170722: i386 DVD 1] stretch/main i386 base-files i386 9.9+deb9u1

If you already have a previous version of the CD you are

present in the new image, and you do not need to download them
again. Mount the old CD ROM and enter the path it is mounted under
(e.g. `/mnt/cdrom').
Alternatively, just press enter if you want to start downloading
the remaining files.
Files to scan:

Note that jigdo does not like the https URL, which is what the (official?) debian instruction page links to. They are both accessible via browser, the only difference being that https uses port 443 while http uses port 80. However, I used the same http jigdo URL for the 9.0.0 images that do not have a problem.

So I guess I am still stuck :(

If jigdo completed successfully, then your image files should be OK, because they will have been verified.

Meanwhile, in the Debian/apt source code, I find a reference to an “APT::Get::AllowUnauthenticated” option, which you should be able to specify on the apt-get command line:
Code: Select all
apt-get --allow-unauthenticated ......

As a last resort, perhaps you could try that?

The man pages for apt-get say --allow-unauthenticated is just the global equivalent of "trusted=yes", and indeed, using it does not help.

Re: Stretch upgrade 9.0.0 to 9.1.0 fails from update DVD

Postby gurfle » 2017-08-03 15:14

It looks like there is a bug in the 9.1.0 update DVDs (at least for i386 and amd64, both of which I have tried):

With DVD 1 (non-update) for 9.1.0 made using jigdo, the upgrade succeeds.
So I just edited the title of this thread to reflect that the problem is with upgrading from the update DVD.

This is annoying though, as I do not want to have to make 14 DVDs all over again just to get an upgrade.

Anybody have suggestions? Should somebody in the official debian package maintenance group be notified?

I’m afraid I’m out of inspiration. According to the APT source code, the error that you encounter is generated when the failure reason is set to “WEAK_HASHSUMS”:
Code: Select all
switch (failreason)
{
   .
   .
   .
   case WEAK_HASHSUMS:
      out << _("Insufficient information available to perform this download securely") << std::endl;
      break;
   .
   .
   .
}
There does not seem to be any option to ignore this condition.

I have no idea why this error does occur on the update DVD, while it does not on the regular 9.1.0 DVD. As far as I can tell, there is nothing missing on the update DVD that is included on the regular one, and the checksums that are recorded in the “Release” file are correct in both cases (at least for those files that exist).

In case you’re curious, or if you want to verify the checksums for yourself, here’s how I verified them:
  • Mount the (update or regular) DVD to some location—which I will call “${MOUNTPOINT}” below.
  • Enter the “dists/stretch” subdirectory of said mountpoint:
    Code: Select all
    cd "${MOUNTPOINT}"'/dists/stretch'
  • Verify the sha512 checksum of the files listed in the “Release” file:
    Code: Select all
    sed --regexp-extended --silent --expression='s/^[[:space:]]*([[:xdigit:]]{128})[[:space:]]+[[:digit:]]+[[:space:]]+(.+)$/\1  \2/p' Release | sha512sum -c
On the update DVD, all files pass the verification. On the regular DVD, all existing files also pass verification, but some files are missing.

Just to be sure, I also verified the sha256, sha1, and md5 checksums recorded in the “Release” files—with the same results:
Code: Select all
sed --regexp-extended --silent --expression='s/^[[:space:]]*([[:xdigit:]]{64})[[:space:]]+[[:digit:]]+[[:space:]]+(.+)$/\1  \2/p' Release | sha256sum -c
sed --regexp-extended --silent --expression='s/^[[:space:]]*([[:xdigit:]]{40})[[:space:]]+[[:digit:]]+[[:space:]]+(.+)$/\1  \2/p' Release | sha1sum -c
sed --regexp-extended --silent --expression='s/^[[:space:]]*([[:xdigit:]]{32})[[:space:]]+[[:digit:]]+[[:space:]]+(.+)$/\1  \2/p' Release | md5sum -c

Sure looks to me like a bug report is in order.
I wouldn’t mind creating it if I had a system on which I could reproduce the error, but since I’m running Debian Testing, it doesn’t apply to me.

I guess I could, but I'll need a tip on how to begin (such as instruction page, where to post, send e-mail etc.).

To report a bug, see: Reporting Bugs.

I believe that the reportbug tool will collect some amount of data on your configuration, so you are supposed to use it on a system that shows the issue that you are going to report.

same words, or the question into your favourite search engine, or you can actually
just type them in directly,...

You will see it results in a list of various links to sites that have instruction pages, and
tutorials.
The first one is : https://www.debian.org/Bugs/Reporting
and there are several others.
The same applies to :
