Thanks for your bugreport.

Could you please remove the files in /var/cache/apt/*.bin and see if that fixes the issue? Does apt-cache search foo or some similar command crash too?

[Julian Andres Klode (juliank)]

Most likely an APT bug.

[Julian Andres Klode (juliank)]

The objects seem to be correct, so that's likely an invalid cache file. Closing, as this just clutters up the bug list.

[Shahar Or (mightyiam)]

Dear Julian,

This bug report, with 9 duplicates and many subscribers is due to an invalid cache file?

Blessings,
Shahar
