Re: check if a newer version of a package is available

1) How do I check if a newer version of a package is available from a

I'm not sure there but my guess would be to use one of the CPAN modules
related to APT, perhaps Linux::APT
2) Generalizing the previous question, is there any way to get the
version number of the package to which it will be upgraded to had I
run sudo apt-get install PACKAGE?
apt-cache would do that. For xterm,
apt-cache policy xterm
or something like this
apt-cache policy xterm \
| awk '$1 == Installed: { installed = $2 } \
$1 == Candidate: { candidate = $2 } \
END { if ( installed candidate ) { print candidate } \
else { print 0 } }'

Personally and just about permissions, I would be more strict, like

You have to leave read permissions for the web server to be able serve up
the web pages. That means 775 or 755 for directories and 664 or 644 for
files.

Put what you would have put inside .htaccess inside the appropriate
Directory directive inside the web server's configuration file. Remember
to reload. .htaccess is only for when you don't actually have write

How APT signs packages
Hi, Where can I find an uptodate description of exactly how PGP is used by APT in packaging?

What is the real situation? That is true. As described here[1], the package checksums are stores in the Packages file, the checksums for the Packages file are stored in the Release file and the release file is GPG signed. So you have a chain of fidelity from Releases to the package and a chain of trust from yourself to the Releases. [1] http://wiki.debian.org/SecureApt Thanks. The weak point, relatively speaking, looks to be the MD5 checksums in Releases. The link above [1] says MD5 is now a broken hash function, and should be replaced for all security-minded usages. Out of curiosity, what are the plans then for moving up to SHA256 or better? Regards, /Lars -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Thanks. One comment claimed that from Lenny onwards SHA256 checksums
would be used. But in Squeeze, *_Release still has MD5 checksums, at
least for the repository I have. So it looks like the infrastructure
supports SHA but it's still needed to do the tedious work of migration.
Is there any archive of why the move was not made for Lenny or later?
