[Aptitude-devel] Bug#670479: [aptitude] 'aptitude update' stucks at communication with /usr/lib/apt/methods/http

[Takahide Nojima]

Package: aptitude
Version: 0.6.6-1+b1
Severity: normal

--- Please enter the report below this line. ---
Hi,

I'm currently using aptitude and apt installed from experimental package.

Recently upgrading both package, I find 'aptitude update' seem to hang up.

It seems that there are some problems of communication between
aptitude and /usr/lib/apt/method/http. Using strace command,both aptitude and
/usr/lib/apt/method/http stuck at select(1,[0],NULL,NULL...). They seems to wait 
for some message each other from pipes forever.

Otherwise 'apt-get update' works fine. 

Does anyone know workaround for this problem?

Thanks in advance,

Takahide Nojima
