Já tentei reinstalar:

sudo apt install --reinstall snapd && sudo snap refresh

sem sucesso.

Ubuntu 24.10

Alguma ideia?

$ whereis pip

pip3.6 apareceu depois:

$ sudo su
$ update-alternatives --install /usr/bin/python python /usr/bin/python3 1

Em ambientes anaconda, o pip funciona bem.

A exclusão de coisas relacionadas ao python, em uma extensão segura - sem quebrar o sistema e reinstalar as coisas corretamente, é uma solução preferível? E como fazê-lo?

Eu sei que existem muitas perguntas semelhantes, mas já tentei muitas coisas (obviamente, estraguei alguma coisa) e não consegui resolver o problema.

Obrigado!

Eu sei que esta pergunta é feita antes, mas nada parece funcionar. Eu tenho um Windows 10 de inicialização dupla - ubuntu 18.10 no NVME e uma segunda unidade de disco rígido de 1 TB (ntfs). É claro que o Windows tem permissão no HDD, mas o Ubuntu não (somente leitura).

Eu quero ter permissão de leitura-gravação-execução como usuário (id=1000) no HDD!

tentou:

  1. remontar

    sudo mount -o remount,rw Às vezes funciona após a primeira reinicialização, mas após a segunda reinicialização, eu tinha permissões somente leitura novamente

  2. editar fstab

entrada padrão:

/dev/disk/by-uuid/[disk-id] /caminho/para/montar auto nosuid,nodev,nofail,x-gvfs-show 0 0

alterado para:

/dev/disk/by-uuid/[disk-id] /caminho/para/montar auto nosuid,rw,nodev,nofail,x-gvfs-show 0 0

,

/dev/disk/by-uuid/[disk-id] /caminho/para/montar auto nosuid,uid=1000,nodev,rw,nofail,x-gvfs-show

,

/dev/disk/by-uuid/[disk-id] /path/to/mount ntfs defaults

,

/dev/disk/by-uuid/[disk-id] /path/to/mount ntfs-3g defaults

,

dev/disk/by-uuid/[disk-id] /caminho/para/montar ntfs nosuid,uid=1000,nodev,rw,nofail,x-gvfs-show 0 0

  1. chown

    sudo chown -R -v usuário:usuário /caminho/para/montar

erro: falha ao alterar a propriedade de '/path/to/mount' de user:root para user:user ,

chown -R user /path/to/mount

não funcionou

Pelo que entendi, as permissões são concedidas na montagem no momento da inicialização. Portanto, a solução deve estar no fstab. Mas, o ponto de montagem está em /media/ (ou por padrão em /mnt/) que são diretórios com permissões somente de root, então tentei montar em /home/user/testDir, mas recebi o erro:

mount: /home/user/testDir: ponto de montagem não montado ou opção ruim

Alguma sugestão? Talvez, em como editar corretamente o fstab? Qualquer ajuda será profundamente apreciada.
