[WSL] How to resolve Operation not permitted error on cloning a git repository

January 6, 2021 less than 1 minute read

A quick tip!

I just reinstalled Ubuntu WSL on my freshly-formatted laptop. Everything seemed to be working properly but I ran into an annoying problem cloning one of my git repository:

Cloning into 'alessandrococco.gitlab.io'
error: chmod on /mnt/c/Users/alessandro/Projects/alessandrococco.gitlab.io/.git/config.lock failed: Operation not permitted
fatal: could not set 'core.filemode' to 'false'

[SPRING] How to pass a list of tuples to a IN clause using NamedParameterJdbcTemplate

    IN (('AAA', 111, 'X'), ('BBB', 222, 'Y'))

While I was coding I had a doubt: is the NamedParameterJdbcTemplate able to handle it? Fortunately, yes, it does! How? The answer is more trivial than expected!
