Unable to Compress MP3 with Flac

I am trying to use FLAC to compress an mp3 file like below:

flac -8 1-5f15c799beb953837480f0e29d872eb9.mp3

However, I keep getting the error

: input file 1-5f15c799beb953837480f0e29d872eb9.mp3 has an ID3v2 tag

. I have read through numerous stack exchange answers such as this , this , or this . One of the answers suggested using ffmpeg but I received an error regarding something with tags. I then tried using eyeD3 but when I installed it with pip3 install, I wasn't able to run the binary file. The most promising approach was using ip3v2. I did

apt-get install ip3v2

and then ran

-s 1-5f15c799beb953837480f0e29d872eb9.mp3

which gave the ouptut

Stripping id3 tag in "1-5f15c799beb953837480f0e29d872eb9.mp3"...id3v1 stripped.

When I tried running the flac command again, it failed again saying that ID3v2 tags were still present. Does anyone have any ideas on where I can strip these ID3v2 tags?
