TL;DR use sort -b -k 2
From man sort:
"A field is defined as a maximal sequence of characters other than the
field separator and record separator (newline by default). Initial
blank spaces are included in the field unless -b has been specified; the
first blank space of a sequence of blank spaces acts as the field
separator and is included in the field (unless -t is specified). For
example, all blank spaces at the beginning of a line are considered to
be part of the first field."

because there are more blank spaces in front of the dates. Only when
package names have the equal number of letters the dates get sorted as
