Same happens on codium-1.46.0-1591900444.el7.x86_64 on Fedora 32 x86_64 when trying to install ms-vscode.cpptools. Downgrade to codium-1.45.1-1589539729.el7.x86_64 fixed this.

I'm having a similar issue. It doesn't tell me it failed, but it doesn't actually add the extension.

Even if it's present in my ~/.vscode/extensions folder, it's not loaded in VSCodium.

Downgrading to 1.45.1 fixed it for me.

Seems to be related to https://github.com/VSCodium/vscodium/issues/421.

Workaround: https://github.com/VSCodium/vscodium/blob/master/DOCS.md#extensions-marketplace

Probably related to the new store yes. However, even installing with a VSIX fails for me.

I'm specifically trying to install the rust-analyzer extension.

Same issue on macOS Catalina. But I should mention installation within VSCodium very fast, like all extensions just disabled and built-in

This workaround https://github.com/VSCodium/vscodium/issues/418#issuecomment-643664182 works for this issue too

same here

➜  ~ vscodium --install-extension Shan.code-settings-sync   
Installing extensions...
Cannot read property 'length' of null

In gui cant even find any extension with sync word:

I think this problem had the same cause as https://github.com/eclipse/openvsx/issues/143. It should work now, please verify.

actually as I can see open-vsx.org does not have as many extensions as official repo marketplace.visualstudio.com has... I cant even find Settings Sync, SqlLite manager plugin etc...
