Updating expired GPG keys and their backup 🔑🔐💻

I use a GPG key to sign my git commits.

An error like this one might be a sign of an expired GPG key.

error: gpg failed to sign the data fatal: failed to write commit object

Renew GPG key

Given that your key has expired.

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

# check if file-based sessions are enabled
file_storage=$(/usr/lib/php5/sessionstorage | grep '^files$' -c)
if [ "$file_storage" = "0" ]; then
    exit 0
fi


# first find all used files and touch them (hope it's not massive amount of files)
