Best Answer

Albert is my favorite quick launcher, so I have it installed in Ubuntu 18.04. The errors you are getting appear to reflect temporary or perhaps permanent problems with the PPA.

Installing through PPA

The User guide of Albert refers for more instructions to a site of openSUSE. There, you click on the Ubuntu icon. You will find instructions there to connect to a PPA that is different than the one you attempted.

Installing through a .deb installation file

I prefer to install Albert by downloading a .deb installation file. The advantage is that you do not need to add an external PPA. The drawback is that the program will not automatically be updated as new versions appear. Depending on how you see it, this might actually be an advantage. Albert is in strong development, and a new version may sometimes have issues.

The second link on the page, "Grab binary packages directly", allows you to download 64 bit or 32 bit .deb installation files.. Right-click the downloaded .deb and select "Open with software installer". This will install the .deb file using Ubuntu software.

Ubuntu – get an error trying to install php5-intl

Force the installation of version 5.5.9+dfsg-1ubuntu4

sudo apt-get install php5-common=5.5.9+dfsg-1ubuntu4

Version 5.5.9+dfsg-1ubuntu4 can't be installed in the normal way, because your installed version has a higher version number.

After reading your comments and your updated question, your system is pretty shot up. Why do you use PPAs or install deb files if you do not know how to handle it?

I suspect you've used PPAs from here. Therefore

Re-add the PPAs

Upgrade your system. We need a defined state

sudo apt-get update
sudo apt-get dist-upgrade

Decide whether you want to keep the PPAs
- If your answer is yes, stop here
- If your answer is no, read on
  
  Install a little helper
```
sudo apt-get install ppa-purge
```
  Purge the PPAs, eg ppa:ondrej/apache2
```
sudo ppa-purge ppa:ondrej/apache2
```
  Repeat the previous step for all PPAs that you do not want to keep

Ubuntu – Wine won’t install, Does not have valid release file

18.04 has been out for less than a week. As such, many developers haven't caught up to the new release yet. To that end, WineHQ has a bug for this already requesting 18.04 packaging in their repository.

There is Wine 3.0 in the Ubuntu repositories, you can use that in the interim by executing sudo apt install wine. Once the upstream WineHQ repositories catch up you can use them.

Once that time is available, you can follow the instructions for installing from their repos. From their instructions page are the instructions to follow at that time:

If you have previously installed a Wine package from another repository, please remove it and any packages that depend on it (e.g., wine-mono, wine-gecko, winetricks) before attempting to install the WineHQ packages, as they may cause dependency conflicts.

If your system is 64 bit, enable 32 bit architecture (if you haven't already):
sudo dpkg --add-architecture i386 
Add the repository:
wget -nc https://dl.winehq.org/wine-builds/Release.key
sudo apt-key add Release.key
sudo apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/
Update packages:
sudo apt-get update
Then install one of the following packages:

Stable Branch:
sudo apt-get install --install-recommends winehq-stable
Development Branch:
sudo apt-get install --install-recommends winehq-devel
Staging Branch:
sudo apt-get install --install-recommends winehq-staging
If apt-get complains about missing dependencies, install them, then repeat the last two steps (update and install).

Staging isn't really used anymore, so use either Stable or Devel.

There will be differences though:

Files are installed to /opt/wine-devel.

Menu items are not created for Wine's builtin programs (winecfg, etc.), and if you are upgrading from a distro package that had added them, they will be removed. You can recreate them yourself using your menu editor.

Binfmt_misc registration is not added. Consult your distro's documentation for update-binfmts if you wish to do this manually.

WineHQ does not at present package wine-gecko or wine-mono. When creating a new wine prefix, you will be asked if you want to download those components. For best compatibility, it is recommended to click Yes here. If the download doesn't work for you, please follow the instructions on the Gecko and Mono wiki pages to install them manually.
