This looks to me more like something that's seriously wrong with your system rather than a problem with the package:
Setting up libkadm5clnt6 (1.7dfsg~beta3-1ubuntu0.6) ... dpkg (subprocess): unable to execute installed post-installation script: Exec format error The postinst script for that particular package should be just a regular shell script. That sounds like disk corruption or some similar problem which is making the postinst script look like a corrupt binary. -- package libkadm5clnt6 1.7dfsg~beta3-1ubuntu0.6 failed to install/upgrade: https://bugs.launchpad.net/bugs/625651 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
