Upgrade 7.17->7.19 OK on WS, fails Laptop

[Quoth]

Same OS (Mint 21.3 with Mate) on WS (Workstation) and 7.19 upgrade was OK on it. I skipped 7.18

Fails on laptop.

Your system is missing the FreeType library libfreetype.so. Try installing the freetype package.

Your system is missing the FreeType library libfreetype.so
Except it's not missing libfreetype.so and upgrade to 7.17 was OK (whenever that was).

The 7.17 is running on the laptop. But the update download and install script fails for any version.

The symantic package manager seems to indicate libfreetype6 is installed. I reinstalled it, but that made no difference.

Amusing. I had no issue installing on chromeos HOWEVER I was using an old copy of the linux_installer.sh script...

My version was missing the check for the presence of libfreet

def check_for_recent_freetype():
    import ctypes
    try:
        f = ctypes.CDLL('libfreetype.so')
    except OSError:
        raise SystemExit('Your system is missing the FreeType library libfreetype.so. Try installing the freetype package.')
    try:
        f.FT_Get_Color_Glyph_Paint
    except AttributeError:
        raise SystemExit('Your system has too old a version of the FreeType library.'
                         ' freetype >= 2.11 is needed for the FT_Get_Color_Glyph_Paint function which is required by Qt WebEngine')

I do NOT have libfreetype.so present; but I do have libfreetype6.so

It's worth noting this addition to the install script was made today.

[Quoth]

So the install script changed today, hence the install of 7.19 on WS a few days ago worked (and Calibre 7.19 works), but fails this evening on the laptop.

If I alias libfreetype6.* to libfreetype.* it would work?

[PeterT]

No idea sorry

[Tlman46]

Same problem here. Frustrating!

[Quoth]

It will be fixed soon

[Quoth]

Yes, the install script now has same error on WS, which was fine installing 7.19 a few days ago.

[Quoth]

I can't remember ever doing python.

This is obviously doing the wrong check.

def check_for_recent_freetype():
    import ctypes
    try:
        f = ctypes.CDLL('libfreetype.so')
    except OSError:
        raise SystemExit('Your system is missing the FreeType library libfreetype.so. Try installing the freetype package.')
    try:
        f.FT_Get_Color_Glyph_Paint
    except AttributeError:
        raise SystemExit('Your system has too old a version of the FreeType library.'
                         ' freetype >= 2.11 is needed for the FT_Get_Color_Glyph_Paint function which is required by Qt WebEngine')

I downloaded the "linux-installler.sh" and simply commented it all out (a # at the start of each line just in that listed block ("def check_for_recent_freetype():") after the "import ctypes" and then saved it and ran it and it worked.

I've no idea what it should be checking for (it's not 'libfreetype6.so'), or if the checking code is correct.

That worked. Downloaded and edited the installer.
Mint 22.
