Hello everyone,
I had this error yesterday when i wanted to restore the backup of all my personal files.
Can someone have an idea of what I could do to restore all my data ?

GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: données chiffrées avec AES
gpg: chiffré avec 1 phrase secrète
gpg: block_filter 0x000055613ba13570: read error (size=9188,a->size=5092)
gpg: Attention : le message chiffré a été manipulé.
gpg: block_filter: pending bytes!
===== End GnuPG log =====

Even if you have just a clue, I take it :)

    I can provide more details about my situation if it can help.

    I was on Ubuntu 16.04 when I save all my /home.
    Then I copy the archive on my external HD.
    And now, I am on Ubuntu 17.10, and I can't decrypt my data :/

    Can someone have a clue ? The block_filter error may be linked with corrupt data. Is that correct ? and in that case, can I arrange this ? Thanks for the help, I really need my files back.

    I copy the GPGError again, but in english.

    Synchronizing remote metadata to local cache...
    GnuPG passphrase for decryption:

    Hi neoz,

    it's best to direct any Linux related questions to the gnupg-users mailing list.
    They are best equipped to help you.

    Hope that helps.
