سلام دوستان
سرور من رو ایران بود و رو main تغییرش دادم تا افزونه ی فلاش پلاگین رو روی کرومیوم نصب کنم.
و بعد خواستم برگردونم رو اسم ایران که دیدم نیست و برای برگردوندنش توی انجمن ها گشتم و کلا لیست مخازن ها رو بهم ریختم. و الان کلا نرم افزارهای سافتوار نصب نمیشن.
دستور آپدیت رو از طریق ترمینال زدم ولی این خطا رو میده:
