I have installed I2P from debian buster repos. and i have tried to reconfigure the memory usage through dpkg and thats what i have got:

user@host:~$ sudo dpkg-reconfigure i2p
perl: warning: Setting locale failed.

is this my machine issue or something missed in I2P?

I believe this is not a package issue.

I guess maybe this?: ​https://askubuntu.com/questions/599808/cannot-set-lc-ctype-to-default-locale-no-such-file-or-directory

but using the same command when i install i2p for i2p official repos , it doesnt show the same thing.

so i think something missing with the buster repo?

Solution:

1- sudo dpkg-reconfigure locales

then choose en_US.UTF-8 UTF-8 - then ok - then choose en_US.UTF-8 then press Enter.

OR

2- sudo apt install locales-all
