我非常喜欢 geany 文本编辑器。但是，我不喜欢的一件事是，当我使用 C/C++ 编写代码时，自动关闭括号选项在类似类型的括号内不起作用。
这是一个例子：
int main()
{
if()
{ // at this point the curly bracket does not auto close - how do I fix that?
}
我正在使用 Ubuntu 20.04 和 Geany 1.36 版。
当我突然更新时，该过程因消息而中止：
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.
