How To Fix existDB: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu existDB is provided by meryl package.

meryl is:

meryl computes the kmer content of genomic sequences. Kmer content is represented as a list of kmers and the number of times each occurs in the input sequences. The kmer can be restricted to only the forward kmer, only the reverse kmer, or the canonical kmer (lexicographically smaller of the forward and reverse kmer at each location). Meryl can report the histogram of counts, the list of kmers and their counts, or can perform mathematical and set operations on the processed data files.
