how to backtrack after attempt to install wrong versoin of an app

[ginahoy]

I need to install Adobe Air to support an application. I followed the instructions on this page, but for the wrong Linux Mint version. Before installing the correct version, I want to remove any trace of the failed installation. I located and erased the .deb file, but I'm not sure if the failed dpkg install command would have generated any folders or files before it aborted. My terminal log is copied below. Am I good to go, or is there anything else I need to do?

Code: Select all

david@linux-desktop ~ $ wget -O adobe-air_amd64.deb http://drive.noobslab.com/data/apps/AdobeAir/adobeair_2.6.0.2_amd64.deb

Do you use Timeshift?

[ginahoy]

Do you use Timeshift?

Not sure what that is, so no.

[gittiest personITW]

Just to check if you do use it.....

Menu
type "timeshift"

If it comes up you're laughing if it has been set up correctlly.
Click on a backup that was made before your 'upgrade', Click RESTORE.

or Aptik?

If however you haven't got Timeshift or Aptik, have you tried the correct version and see if it is ok - it might be a lot of worry over nothing. If you can't install the correct version, then can go from there.

[ginahoy]

I'm not familiar with either app and neither is installed on my system. I have my own backup protocal based in part on Clonezilla, and in fact, I just made a full backup last night. But hopefully there's no need to restore my drive.

No, I haven't tried to install the correct version of Adobe Air. It may very well be fine. I just thought it would be prudent to remove whatever mods to my system the initial attempt may have caused. So I guess my question is whether dpkg might have taken any action before aborting due to dependencies. But you're right, this is probably much ado about nothing. Being new to Linux, I do tend to be overly cautious.

It doesn't look like your attempted installation did anything, but you always run sudo apt purge adobeair, just to be safe.

EDIT: from your link, it looks like you have the correct version of the deb.
EDIT #2: the install instructions required you to run sudo apt-get install -f afterwards; this was to fix any broken dependencies.

[ajgringo619]

All of the missing packages are available in Mint 19.1. If you want, after purging, try the installation again, but install the dependencies first:

Code: Select all

sudo apt install libbz2-1.0:i386 libgtk2.0-0:i386 libnss3:i386 libxaw7:i386 libxslt1.1:i386

EDIT: from your link, it looks like you have the correct version of the deb.

From the link, and the OP's sig, they should be downloading and running the install script.

You are so correct; didn't even think to look there.

I forgot to say, I also agree with this:

Thanks for the replies! I tried the purge command and got this:

Code: Select all

david@linux-desktop ~ $ sudo apt purge adobeair

Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  adobeair*
0 upgraded, 0 newly installed, 1 to remove and 17 not upgraded.
After this operation, 47.2 MB disk space will be freed.
Do you want to continue? [Y/n] n
Abort.

Help me interpret this. I count 18 files in the list. Apparently one of these files would be removed as it wasn't previously installed, and the other 17 would not be upgraded. Does that mean those 17 files existed before the install and the purge will revert to their previous versions? Should I proceed?

I probably should have posted this under the Newbie forum as this is totally new to me

[MrEen]

The important part is this:

Code: Select all

The following packages will be REMOVED:
  adobeair*
0 upgraded, 0 newly installed, 1 to remove and 17 not upgraded.

Type y and let it uninstall.

The other packages are no longer needed on your system, and may not have come from adobeair (I'm not sure on that) but when you want to you can use apt autoremove to remove those as well.
