Subject: latex-cjk-japanese-wadalab.preinst: misuses dpkg --compare-versions

Date: Sat, 30 Apr 2011 18:49:06 -0500

Package: latex-cjk-japanese-wadalab
Version: 0.20050817-15
Severity: minor
Justification: cosmetic

When installing latex-cjk-japanese-wadalab:

| (Reading database ... 152050 files and directories currently installed.)
| Preparing to replace latex-cjk-japanese-wadalab 0.20050817-15 (using .../latex-cjk-japanese-wadalab_0.20050817-15_all.deb) ...
| dpkg: error: version 'latex-cjk-japanese-wadalab_0.20050817-14' has bad syntax: version number does not start with digit
| Unpacking replacement latex-cjk-japanese-wadalab ...
| Setting up latex-cjk-japanese-wadalab (0.20050817-15) ...
| Running mktexlsr. This may take some time... done.
| Processing triggers for fontconfig ...
| Processing triggers for tex-common ...
| Running updmap-sys. This may take some time... done.
| Running mktexlsr /var/lib/texmf ... done.

I suspect future dpkg versions will change the conditions when that error
is emitted, but anyway, in this example it is pointing to a real bug:
"dpkg --compare-versions" wants a version number, which in this case would
be 0.20050817-14 rather than that longer string.

Perhaps this would be worth a lintian check?  Cc-ing the lintian
maintainers just in case.

The fix might be as simple as changing

    if dpkg --compare-versions "$2" le "latex-cjk-japanese-wadalab_0.20050817-14"; then

to

    if dpkg --compare-versions "$2" le "0.20050817-14"; then

or removing the conffile removal code in preinst altogether (who is
upgrading from such old versions?).

Thanks for keeping Debian working well in Japanese.

Regards,
Jonathan

Hi Jonathan

Thank you for your bug report!  It has been a while since I last
checked this package with the current Debian release.
I will have a look at it this week.

Cheers

Thank you.  I think this was fixed by r5264 (use maintscript to
remove both old updmap.d files, 2012-03-22).
