Impossible to install extensions

OS/Platform

Debian, Ubuntu, and derivatives

Installed

Compiled from source

Version

116.0.5845.111

Have you tested that this is not an upstream issue or an issue with your configuration?

• I have tried reproducing this issue in Chrome and it could not be reproduced there
• I have tried reproducing this issue in vanilla Chromium and it could not be reproduced there
• I have tried reproducing this issue in ungoogled-chromium with a new and empty profile using --user-data-dir command line argument and it could not be reproduced there

Description

Extension mime handling is unavailable, so it is impossible to install extensions.

How to Reproduce?

1. Go to chrome://flags/#extension-mime-request-handling
2. OR run UGC with the flag --extension-mime-request-handling=install-always

Actual behaviour

The mime request handling is disappeared from the flags and the passed flag has no effect.

Expected behaviour

Install the CRX.

It's still there for me:

Yeah, but I'm using the official binaries for Windows, so I'd say it's likely something in your self-compiled build. Can you test any of the contributed Linux binaries from https://ungoogled-software.github.io/ungoogled-chromium-binaries and see whether the problem persists there as well? By "any" I mean either "Linux AppImage 64-bit" or "Portable Linux 64-bit" because only these two are at the v116 version right now.

I can't. They are compiled with GTK3 at system/package level and GTK3 is exiled from my system at system/package level; i only have it in an isolated directory which i pass to Chromium at compiling and running.

I built it with these flags though:

Have you forgotten to apply patches/extra/ungoogled-chromium/add-flag-to-configure-extension-downloading.patch?

[TCH68k]

If it is in the ungoogled-chromium repository, then no; i clone the repo and systematically apply all patches:

git clone https://github.com/Eloston/ungoogled-chromium/
cd ungoogled-chromium
git checkout "$CHROME_VERSION""-1"
cp flags.gn ../flags.gn.bak
cd ..
find ungoogled-chromium/patches/ -name '*.patch' -exec mv {} ./ \;
rm -rf ungoogled-chromium
for PATCH in *.patch;
do
	patch -p1 -f < "$PATCH";
done
rm *.patch

[PF4Public]

Please follow the procedure, otherwise you'll have to solve such issues yourself.

Now hold on for a moment. If there is a python script for applying the patches, then why did you ask if i forgot to apply a patch?
Also, does this mean, that the reason this flag is missing, that google took it out from Chromium and it is patched back in UGC?

Actually i already "solved" it: i can download the CRX, unpack it and then load it unpacked. But that is rather a workaround.
