如何处理“gvfs-backends”？

  • 772

我最近将我的 Ubuntu-mate 18.4 更新到了 20.4。几天后，当 Ubuntu 启动时，出现了一个警告，提示它应该安装“gvfs-backends”，但是，当按下“安装”时，出现一个警告，表明这个软件可能会导致问题，并且它不是来自可靠的消息来源 。我应该怎么办？我包括请求的命令及其输出：

$ dpkg -l | grep -i gvfs
ii  gvfs:amd64                                    1.44.1-1ubuntu1                       amd64        userspace virtual filesystem - GIO module
ii  gvfs-common                                   1.44.1-1ubuntu1                       all          userspace virtual filesystem - common data files
ii  gvfs-daemons                                  1.44.1-1ubuntu1                       amd64        userspace virtual filesystem - servers
ii  gvfs-fuse                                     1.44.1-1ubuntu1                       amd64        userspace virtual filesystem - fuse server
ii  gvfs-libs:amd64                               1.44.1-1ubuntu1                       amd64        userspace virtual filesystem - private libraries

按照你的指示，我重复了一遍：

$ grep -r "^deb " /etc/apt/ --include="*.list"

/etc/apt/sources.list:deb http://archive.ubuntu.com/ubuntu focal main
/etc/apt/sources.list:deb http://archive.ubuntu.com/ubuntu focal-updates main
/etc/apt/sources.list:deb http://archive.ubuntu.com/ubuntu focal-backports main
/etc/apt/sources.list:deb http://archive.ubuntu.com/ubuntu focal-security main

到命令：

sudo apt-get install gvfs-backend

答案（谷歌翻译成英文）是：

Reading package list ... Done
Creating dependency tree
Reading the status information ... Done.
Do not can instal some pack. This may mean that
you asked for an impossible situation or, if you are using the distribution
unstable, that some required packages have not yet been created or have been pulled from "Incoming".
The following information can help resolve the situation:

The following packages have unmet dependencies:
  gvfs-backends: Depends: libsmbclient (> = 2: 4.10.0 + dfsg) but it won't install
E: Problems could not be corrected, you have retained broken packages.

enrique@enrique-PC:~$ sudo aptitude install gvfs-backends
Se instalarán los siguiente paquetes NUEVOS:      
  gvfs-backends libcdio-cdda2{a} libcdio-paranoia2{a} libldb2{a} 
  libpython3.8{ab} libsmbclient{a} libtalloc2{a} libtevent0{a} 
  libwbclient0{a} python3-talloc{a} samba-libs{a} 
0 paquetes actualizados, 11 nuevos instalados, 0 para eliminar y 3 sin actualizar.
Necesito descargar 7.763 kB de ficheros. Después de desempaquetar se usarán 33,8 MB.
No se satisfacen las dependencias de los siguientes paquetes:
 libpython3.8 : Depende: libpython3.8-stdlib (= 3.8.10-0ubuntu1~20.04) pero 3.8.12-1+bionic1 está instalado
Las acciones siguientes resolverán estas dependencias

     Mantener los paquetes siguientes en la versión actual:
1)     gvfs-backends [Sin instalar]                        
2)     libpython3.8 [Sin instalar]                         
3)     libsmbclient [Sin instalar]                         
4)     python3-talloc [Sin instalar]                       
5)     samba-libs [Sin instalar]

    运行以下命令来修复您的sources.list：

    sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted

sudo apt-get update
sudo apt-get dist-upgrade # to get newest dependencies

    然后修复您的 Python 版本以匹配默认的 Ubuntu 存储库与当前版本。使用以下命令：

    sudo aptitude install libpython3.8=3.8.10-0ubuntu1~20.04 libpython3.8-minimal=3.8.10-0ubuntu1~20.04 libpython3.8-stdlib=3.8.10-0ubuntu1~20.04 python3-lib2to3=3.8.10-0ubuntu1~20.04 python3.8=3.8.10-0ubuntu1~20.04 python3.8-minimal=3.8.10-0ubuntu1~20.04

    然后最后安装GVFS包

    sudo apt-get install gvfs-backends
