Ubuntu Server（OpenLiteSpeed）下多版本lsphp扩展包安装失败求助

Hey there, let's work through fixing those package-not-found errors you're hitting when trying to install LSPHP extensions. The core issue here is that Ubuntu's default apt repositories don't host these OpenLiteSpeed-specific PHP packages—they're maintained directly by OpenLiteSpeed, so we need to add their official repo first.

Step 1: Add OpenLiteSpeed's Official Repository #

First, we'll import the repo's GPG key to ensure the packages we download are trusted, then add the repository to your system's apt sources:

# Import the OpenLiteSpeed GPG key
wget -O - https://rpms.litespeedtech.com/debian/lst_repo.gpg | sudo apt-key add -

# Add the repository to your apt sources list
echo "deb https://rpms.litespeedtech.com/debian/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/lst_debian_repo.list

Step 2: Refresh Your Apt Cache #

Now update your apt package index to recognize the new repository:

sudo apt update

Step 3: Re-Run Your Installation Commands #

With the official repo added, you should now be able to install those LSPHP packages without errors. Go ahead and re-run the apt-get install commands you tried earlier.

Quick Note on Package Names #

If you still run into a hiccup with a specific package, double-check the naming—OpenLiteSpeed sometimes uses minor variations from standard PHP package conventions. For most cases though, the names you used should work perfectly once the repo is added.

Step 4: Verify the Installation #

After installation, confirm that the LSPHP versions are set up correctly with:

# Check LSPHP 7.0 version
lsphp70 -v

# Verify other versions similarly
lsphp71 -v
lsphp72 -v
lsphp73 -v
lsphp74 -v
lsphp80 -v

That should clear up all the "unable to locate package" and "no installation candidate" errors you were facing. Let me know if you hit any unexpected snags along the way!
