[SOLVED & Fixed] incompatibility issues with other software: URW wants libcurl3

[Twixter]

My OS is Linux Mint 19, which uses Ubuntu 18.04 repositories.

If I do a system-wide install of URW using the downloaded deb file and the Gdebi installer, my libcurl4 package gets removed and replaced with libcurl3. It also removes all other software which required libcurl4, such as Scilab for example.

The tarball download has the same problem.

I'm not sure if this is the correct forum to ask in, but would it be possible to create a virtual environment, or sandbox, in some local folder, where I can run URW without interfering with my other software?

Thanks in advance.

The answer I found was to install Virtual Box on my machine.

This may be useful information for someone else.

I have this problem also, however virtualbox is unfortunately a poor option for me at this time. I'm unsure if I should be posting here or making a new topic, as this is precisely the same problem which I am having.

Is there a way to bypass this libcurl requirement on installation?

I created a new deb package for you, by changing the "libcurl3" requires to "libcurl3 or libcurl4". As long as the game does not use libcurl in a way incompatible with libcurl4, it should work. Give it a try.

This is the change, for the curious (in the file urw/DEBIAN/control, if you unpack the deb):

Code: [Select]

Depends: libsdl2-2.0-0, libsdl2-image-2.0-0, libsdl2-mixer-2.0-0, bash, libcurl3|libcurl4

Let us know if it works, so Sami can fix the package.

Oh gosh that's fantastic! Thanks so much! This really makes my week I have booted it up successfully and I'll be playing it more soon. Can't wait to get back into the unreal world.

If I may ask, is it complicated to modify a deb in this way?

[koteko]

It's very simple, give it a try

Code: [Select]

# unpack the deb within the urw/ directory
sudo dpkg-deb -R urw_3.51_amd64.deb urw

# now we edit the control file, any text editor will do (change the line as I wrote in previous post)
gedit urw/DEBIAN/control

# save and close that file when you are done

# let's create the new deb, ready to be installed
sudo dpkg-deb -b urw/ urw_3.51a_amd64.deb

@Sami can you please update the package to make either libcurl3 or libcurl4 acceptable requirements, as outlined above?

[Almyon]

Wow, that IS simple. Thanks again, both for the help and the knowledge!

This will get fixed in the next update. libcurl dependency was redundant leftover, requirement will be removed completely.

Fixed - persists in 3.51
