升级错误-- "unattended_upgrade与apt.cache.LockFailedException in_fetch_archives()崩溃:未能锁定/var/cache/apt/ Failed / lock“

Question

当我试图从16.04升级到16.10并打开跟踪时，我会收到一条错误消息：

unattended_upgrade与apt.cache.LockFailedException in_fetch_archives()崩溃: 未能锁定/var/cache/apt/存档/锁

我发现它链接到一个名为unattended_upgrade的python文件。这引用了一个名为cache.py的文件，跟踪显示它在第338行中不起作用，我发现它是这样的：

# get lock
lockfile = apt_pkg.config.find_dir("Dir::Cache::Archives") + "lock"
lock = apt_pkg.get_lock(lockfile)
if lock < 0:
    raise LockFailedException("Failed to lock %s" % lockfile)

try:
    # this may as well throw a SystemError exception
    if not pm.get_archives(fetcher, self._list, self._records):
        return False
    # now run the fetcher, throw exception if something fails to be
    # fetched
    return self._run_fetcher(fetcher)
finally:
    os.close(lock)

这段代码在python 3中，我不知道它是做什么的，也不知道如何修复它，但是它不允许我升级。提前感谢

试一试

sudo rm -f /var/cache/apt/archives/lock
sudo apt-get -f -y remove
sudo apt-get -f -y update

我不确定我是否正确地记住了这些命令，所以只需尝试一下。
