I wonder why does alien need sudo privileges while converting a .rpm file to .deb in a non-privileged directory(eg. my home directory).

Is this a security feature(which I believe is redundant, since installing the package would need dpkg, which needs sudo privileges)?

  • Probably just an oversight as in general you should not need to run as root to convert. With that said, IMO alien should be used only as a last resort. Build from source if at all possible. rpm do not always easily convert to .deb due to naming of libraries, installation scripts, dependency checking, etc. – Panther Oct 14 '13 at 18:56

  • You should probably file a bug report against alien as yours is not really a technical question. – Panther Oct 14 '13 at 18:57

Because packages can contain files owned by different users and I believe the conversion process extracts the files and then builds a .deb from there. Setting the permissions on the extracted files requires root access.

Note that you should be able to use fakeroot to work around this.

  • Because packages can contain files owned by different users - which files, for example? – jobin Oct 15 '13 at 5:10
  • @Jobin, all of them? Most files are owned by root, some are owned by other system accounts. None of them are going to be owned by your uid. – psusi Oct 15 '13 at 13:45
