I do not understand whether you forgot the passphrase that was used to
encrypt your home folder (if so, that is over: you need the password to
decrypt the data!) or the new passphrase. Could you clarify?
To everybody with using Trisquel 7 with an encrypted home folder on a
separate partition and who want to do a fresh install of Trisquel 8: there is
nothing to fear (but backup your data anyway)! From the live system:
select 'Something else" (or whatever it is called nowadays) as an
"Installation type" (or whatever it is called nowadays);
choose your the root partition (probably that of Trisquel 7), i.e., the
partition with the filesystem that will be mounted on /: it will be formatted
and you can change the type of filesystem, if you wish;
choose the partition with Trisquel 7's /home as the analog partition for
Trisquel 8 but do *not* click the box that asks it to be formated;
double-check that the partition with Trisquel 7's /home will *not* be
formatted!
proceed with the installation;
specify the *same* login and the *same* password;
once you reboot in the installed system, your home folder, still encrypted,
has your data.
