Import of old keys

[Bernhard]

Hallo,

For a long time I have used debian sid and gnupg with three keys for
different purposes.

After moving to Ubuntu (OT: for multimedia reasons) I fail to use these
keys with the newly created account. I have access to all the old files
and directories and would like to get some help for the incorporation of
the old keys into the new system.

Thanks a lot!

Bernhard
