This bug has now been fixed in the respin re-release Peppermint-7-20161201
Team Peppermint have discovered a bug in the 16.04 version of APT (1.2.15) which causes the installer to crash with certain locale/keyboard combinations during installation of Peppermint 7 Respin.
As this could result in an unbootable system for a small number of users we’ve taken down the Peppermint 7 Respin ISO’s whilst a fix is applied.
For those already trying to install the Peppermint 7 Respin and getting a crash during the install process, there is a workaround here:
We apologies for any inconvenience caused, and will have a fixed ISO available shortly.
Meanwhile the original version of Peppermint 7 can be downloaded from the “Previous Versions” page here:
