Hi
1-In installing php8 from this tutorials : Multiple PHP Versions – Virtualmin with SUDO command in ubuntu 20.04 TLS Server I faced with error :
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)
What Should I do for that?
2-what command should I use to installing OPcach , php-cache , nginx caches ?
3-With php 8 can I install the Source-Guardian module?
