The chromium-browser metadata needs fixing (as explained in my last
comment) so that libnss3 gets upgraded automatically on "apt-get install
chromium-browser".

Final notes:
- This bug may not occur if you try to install Ubuntu while connected to
Internet.
- The reason why I did a "fresh offline install" was that installing it while
online
takes over a hour on my system, installing offline and then doing the
commands above
took only about 10 minutes. You might want to try to take a look into why
is online
Ubuntu install so slow but that is not the bug I want to report here (I
will file
a different bug for that if I can figure out, how).
- Offline installs are pretty common in
[Desktop-packages] [Bug 1821403] Re: chromium browser crash on fresh offline system install
> chromium-browser requires a newer version of libnss3 than what was
initially installed.
It is the job of the package manager to either upgrade an outdated
version of a dependency package when the user tries to install something
or to ask the user to update the system first and then try again, not to
silently install a package with its requirement missing and leave the
user wondering what exactly happened.
The bug is that apt-get does not know that, probably because the
package-metadata is missing the information. The expected behavior here
is that "sudo apt-get install -y chromium-browser" does also upgrade
libnss3 when the libnss3 version currently installed is not enough to
run chromium-browser. Or to have it report an error saying something
like "your system must be updated before you can install this".
My understanding is that this requirement is not recorded in the
chromium-browser package metadata, so when an user tries to install the
package, the apt-get fails to pull in the correct version of libnss3,
leading to a broken package being installed.
> This is not a bug in chromium or libnss itself.
Agree. The bug in in the chromium-browser package metadata which does
not record the minimal libnss3 version necessary correctly, leading to
apt-get believing that "what was initially installed" is sufficient even
though it is not.
> A half-updated system is in an inconstistent state, and will
> result in undefined behaviours like this crash.
1. The system should be in a consistent state when just being
freshly installed. If it is not, then the official
installation image of the distribution is broken.
There is no updating during the installation process nor
any administrative commands being forcibly aborted
afterwards.
2. If apt-get install brings the system into an
inconsistent state, then the (or one of its
dependencies) has broken or incomplete metadata which
should get fixed. In the case of this bug the
incomplete/broken metadata is missing "minimal version"
for libnss3 in the chromium-browser package dependencies.

The additional attached information was sampled at the time after the
chromium-browser successfully completed its install (and after that was
confirmed by successfully launching it as shown in the terminal session)
so any traces of its misbehavior might be long gone before the
attachments were created.

- Offline installs are pretty common in areas with slow Internet. And by "slow
Internet" I don't mean just rural areas with dialup. My current setup is
Colombian
optical wire from Claro and by watching the RX/TX using ifconfig I can tell
the
download process is taking large pauses on this connection, even for simple
"apt-get

- Another idea why someone might want to install the system offline is that
they don't
want to mess up with connecting to Internet just yet or they want the system
"fresh
as coming from the CD".

[Desktop-packages] [Bug 1798601] [NEW] posix_memalign corrupts heap
Public bug reported: The attached program exposes a bug in posix_memalign that causes it to either silently corrupt heap or cause the memory allocation checker to report spurious failures. I believe that the former is the case here because on more complex software (minetest or Irrlight tutorial examples) I had seen "pointer passed to free() which was never returned by an allocation function" errors. The posix_memalign is used by the OpenGL driver (package: mesa) and can be avoided by compiling mesa from source after telling the package we don't have posix_memalign. The "pointer passed to free()..." error was seen coming from inside the OpenGL as the irrlight example did not do much malloc calls itself. Unfortunately I could not figure out how this "real corruption" could be exposed by a simple program like this as it seems it requires a complicated mixture of malloc() and posix_memalign to trigger. To compile the program run "sh compile.sh" and to run it run "sh run.sh". You will then get two files, "memalign.out" (the output of the program until the failure) and "memalign.log" (a mtrace log). The program shall run for a several seconds but in fact it only runs for about 0.2 seconds before aborting with "invalid pointer" complaint. The program appears to finish normally (with no memory leaks detected) when "-lmcheck" is omitted from the compilation command (see compile.sh). However I had seen crashes caused by the problem in more complicated software that mixes posix_memalign with malloc.
