事出有因
是希望在NixOS上使用微信来着，但是又不想再wine，搜了下flatpak上已经有了wechat universal版，于是想无脑
flatpak install com.tencent.WeChat.flatpak
随后便遇到报错
[user@nixos:~]$ flatpak install flathub com.tencent.WeChat
Note that the directories
'/var/lib/flatpak/exports/share'
'/home/wsl/.local/share/flatpak/exports/share'
are not in the search path set by the XDG_DATA_DIRS environment variable, so
applications installed by Flatpak may not appear on your desktop until the
session is restarted.
Looking for matches…

简单排查
- 使用chrome下载这个连接，得到结果：wechat-beta_1.0.0.238_amd64.debFailed - File incomplete
- 看起来像是自己的问题，然后切换另外一台机器wget这个地址，也是存在报错，推测是上游服务器有问题。
着手解决
首先查找到了 flathub 上wechat包的仓库，在其中搜索这个地址，定位到了具体文件的具体位置 com.tencent.WeChat.yaml 而后克隆此仓库，修改连接
git clone https://github.com/flathub/com.tencent.WeChat.git
cd com.tencent.WeChat
sed -i 's|https://archive2.kylinos.cn/deb/kylin/production/PART-openKylin/custom/partner/openKylin/pool/all/wechat-beta_1.0.0.238_amd64.deb|https://archive2.kylinos.cn/DEB/OPENKYLIN/pool/all/wechat-beta_1.0.0.238_amd64.deb|g' com.tencent.WeChat.yaml
参照 flatpak文档进行本地打包
flatpak remote-add --if-not-exists --user flathub https://dl.flathub.org/repo/flathub.flatpakrepo
# 打包需要flatpak-builder以及appstream
nix-shell -p flatpak-builder
nix-shell -p appstream
# 打包
flatpak-builder --force-clean --user --install-deps-from=flathub --repo=repo --install builddir com.tencent.WeChat.yaml
# 运行
flatpak run com.tencent.WeChat
后续
原先无法下载连接过了一个小时就恢复正常了，也无法确定到底是我自己网络的问题还是上游的问题了。
