[01:45] <enyc> any clue why, qemu-user-static  ** arm64 ** would be failing me on  emulating  xenial chroot only,  trusty and jessie  are fine ?  --   weirdness with apt-get update  doing  "E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Start. Current value: 25165824. (man 5 apt.conf)" ) -- even if you try to 'fix' that with more apt cache-limit ??
[01:48] <enyc> (could be a  xenial-arm64  bug rather than qemu at all of course =) )
[22:16] <enyc> OK I've tried a new qemu chroot of xenial-arm64 post-xenial-release thats' still misbehaving
[22:16] <enyc> apt giving E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Start. Current value: 25165824. (man 5 apt.conf)
[22:16] <enyc> even though I've tried increasing that and all
[22:17] <enyc> and other arm64 chroots (jessie, stretch)  working fine
[23:02] <enyc> Can anybody else get  xenial-arm64  chroot working  on qemu  please? ;-))
