我写了下面的代码来弄清楚malloc和realloc。我已经使用malloc初始化了指针,然后使用realloc,我增加了数组的大小。但是当我运行代码时,我得到了以下错误。
#include<stdio.h>
#include<stdlib.h>
int main()
{
char *p;
p = malloc(10);
p = " this is it";
printf("\n%s", p);
p = realloc(p, 14);
p[11] = 'A';

我刚刚通过Canonical Ubuntu存储库安装了gst-browser ( VisualGST ),所以我尝试通过在命令行运行gst-browser来启动VisualGST。但是,我马上就看到一个错误:

我刚刚把我的Ubuntu从16.04升级到18.04。
当我想从命令行运行VirtualBox时,它不起作用。它返回错误:
VirtualBox: Error -610 in supR3HardenedMainInitRuntime!
VirtualBox: dlopen("/usr/lib/virtualbox/VBoxRT.so",) failed: <NULL>
VirtualBox: Tip! It may help to reinstall VirtualBox.
我已经重新安装了VirtualBox,但是它仍然不能工作。
当然,我已经检查了Stack上

我安装了qBittorrent,但几分钟后它就会随机关闭。没有错误信息或任何东西,所以我不知道它为什么会这样。
我刚开始学习Linux/Ubuntu,所以我对它还不太了解。

我正在尝试执行nft,它是从源构建的,但是它报告
$ nft

我构建了libmnl、libnftnl、nftable,通过运行autogen.sh,然后用以下方式进行配置:
--prefix=/usr/local
这些是/usr/local/lib的内容:
$ ls -l /usr/local/lib/ | grep libnftnl

刚刚重新安装了Ubuntu 21.10,然后通过Samba 4.13.14-Ubuntu:
sudo apt install samba avahi-daemon
每当连接到Samba的macOS客户机重新启动时,我都会收到以下电子邮件:

This means there was a problem with the program, such as a segfa
