"cannot connect to chrome" on Linux after I deleted "/tmp/snap-private-tmp"

[iamumairayub]

I have been using SB for several months, for different clients, across different servers.

with SB(
    uc=True, 
    xvfb=True,
    browser='chrome',
    extension_dir=",".join(extensions),
    ) as sb:
    pass

This code was working perfectly for me but

Its 2nd time where my server's /tmp/snap-private-tmp grew huge, occupying 80% of server disk, I deleted it.

and now I started getting

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:9222 (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I tried updating/reinstalling google-chrome but no use.

I tried headless args but no success

with SB(
    uc=True, 
    xvfb=True,
    browser='chrome',
    extension_dir=",".join(extensions),
    headless=True, #tried False too
    headless2=True, #tried False too
    ) as sb:
    pass

I also tried this but same error

with Display(visible=0, size=(headers_to_use['screen_width'], headers_to_use['screen_height'])):

    driver = Driver(
        uc=True, 
        browser='chrome',
        extension_dir=",".join(extensions),
    )

Here are results of few commands that proves Chrome is there but just Python not being able connect to it.

google-chrome --version
Google Chrome 122.0.6261.111

/usr/bin/google-chrome

Your /usr/bin/google-chrome call had a link to https://crbug.com/638180, which had a useful comment: https://issues.chromium.org/issues/40480798#comment106. So the first time it didn't work, it was because you improperly deleted a necessary directory that was being used by Chrome. Then you had issues because you reinstalled Chrome with different permissions from before (you need a non-root user). That Chromium issue comment had a link to https://code.visualstudio.com/remote/advancedcontainers/add-nonroot-user.

Anyway, this is more of a Linux/Chrome configuration issue than a SeleniumBase one (you did mention your code was working before you made those changes).
