Permissions
snap-store 或基本上任何快照應用程序都無法執行：user-dirs.dirs: Permission denied
我正在執行幾個隨 Snap Store 一起安裝的應用程序。有段時間沒用系統，瞎跑
sudo apt-get update sudo apt-get upgrade sudo snap refresh重啟bdzink後。當我啟動這些應用程序中的任何一個甚至是快照儲存本身時，它都會默默地完成。其他一切都按預期工作。
為了更好地診斷問題，我嘗試使用命令行啟動應用程序：

user-dirs.dirs我的主目錄中的任何其他文件是世界可讀的，但是我更改了權限以檢查會發生什麼：pdebski@system:~/.config$ chmod go+r u*s pdebski@system:~/.config$ ls -ld . drwxr-xr-x 27 pdebski pdebski 4096 cze 5 19:52 . pdebski@system:~/.config$ ls -al u* -rw-r--r-- 1 pdebski pdebski 632 mar 21 2018 user-dirs.dirs pdebski@system:~/.config$ ls -ald ../.c*g drwxr-xr-x 27 pdebski pdebski 4096 cze 5 19:52 ../.config pdebski@system:~/.config$ snap-store /snap/snap-store/415/bin/desktop-launch: line 51: /home/pdebski/.config/user-dirs.dirs: Permission denied 20:45:44:0906 GLib-GIO g_app_info_get_name: assertion 'G_IS_APP_INFO (appinfo)' failed 20:45:44:0951 Gtk Failed to load module "appmenu-gtk-module" Unable to init server: Could not connect: Connection refused 20:45:45:0012 Gtk cannot open display: :1我被困住了。怎麼了？
我有 manjaro 但這個問題已經好幾次了，快速重新安裝快照商店解決了這個問題（嘗試按照他們的說明https://snapcraft.io/snap-store）
現在我有矩形而不是文本字元，我可以通過以下方式解決：
sudo rm /var/cache/fontconfig/* sudo rm ~/.cache/fontconfig/*
謝謝@borabora 確實重新安裝 snap-store 有助於：
$ snap help The snap command lets you install, configure, refresh and remove snaps.

注意不同的錯誤消息 - 顯然快照儲存質量需要更多改進。
可能在系統更新核心或某些庫更新期間破壞了兼容性。無需重新安裝其他 Snap 應用程序。為所有其他應用程序自動重新安裝商店固定的先決條件。
