getting rid of protobuf 3.13.0 in Ubuntu 20.04 and set protobuf 3.6.1 as default

  • 772

I initially installed protobuf 3.13.0 and then used apt remove to remove it but it is not getting removed.

I even installed protobuf 3.6.1 from source following these instructions but still 3.13.0 is in place https://askubuntu.com/a/1072684/165324

    $ protoc --version
    libprotoc 3.13.0

$ tar -xvzf protobuf-all-3.6.1.tar.gz

    I noticed I have:

    $ which -a protoc
/home/mona/anaconda3/bin/protoc
/usr/local/bin/protoc

    I added the last line in ~/.bashrc:

    $ tail ~/.bashrc


alias vi='vim'
aa_prompt_defaults

alias bat='batcat'

alias fd='fdfind'

alias protoc=/usr/local/bin/protoc

    then:

    $ source ~/.bashrc

    now:

    $ protoc --version
libprotoc 3.6.1
