Maybe aegis errors so you need to re-install aegis? Can you try download only then extract the .deb? Aegis .debs: aegis-certman-common-ca aegis-certman-tools aegis-codesigning-ca-001 aegis-crypto-tools, aegis-enabler-enforce aegis-enabler aegis-global-tokens aegis-install aegis-ovi-source-policy aegis-unknown-source-policy aegisfs Although i think aegis-install is sufficient... OR simply download dpkg and extract it? EDIT: I think your refhashlist is screwed? Can you check the hash in refhashlist for /usr/bin/dpkg? Is it the same as the hash for the file you just put in? Edit 2: Despite the errors did the re-installation go thru' successfully?
